Quick Answer
Both bằng and như can translate to 'as' or 'like' in English, but they serve distinct purposes. Bằng is primarily used for comparisons of equality (as...as) and to denote the means or method of an action ('by means of', 'with'). Như is used to express similarity or resemblance ('like', 'similar to') and to introduce examples or illustrations ('such as').

Detailed Explanation
Understanding the nuances between bằng and như is crucial for B1 Vietnamese learners. While both can appear to mean 'as' or 'like', their grammatical functions and semantic fields are quite distinct.
Using Bằng
Bằng (Hán-Việt: 平 'bình' meaning flat, level, equal; or 憑 'bằng' meaning rely on, by means of) is primarily used in two main contexts:
Comparisons of Equality (as...as): When you want to state that two things are equal in degree, quantity, or quality. It signifies 'equal to' or 'the same as'.
Structure: A + [adjective/adverb] + bằng + B or A + [verb] + bằng + B.
Examples:
Căn phòng này rộng bằng căn phòng kia.
This room is as wide as that room.
Tôi làm việc chăm chỉ bằng anh ấy.
I work as hard as him.
Means or Method (by means of, with): To specify the tool, material, or method used to perform an action. It answers the question "how?" or "with what?".
Structure: Verb + bằng + Noun (method/material/tool).
Examples:
Chúng tôi đi du lịch bằng tàu hỏa.
We travel by train.
Cô ấy viết thư bằng bút chì.
She writes letters with a pencil.
Material Composition (made of): To indicate what something is made from.
Example:
Cái ghế này làm bằng gỗ.
This chair is made of wood.
Using Như
Như (Hán-Việt: 如 'như' meaning like, as, if) is used to express similarity, resemblance, or to introduce examples and illustrations. It implies 'similar to', 'in the manner of', or 'for instance'.
Similarity or Resemblance (like, similar to): To describe that something is similar to another thing, or acts in a certain way.
Structure: A + như + B.
Examples:
Anh ấy cao như cha mình.
He is tall like his father.
Cô bé cười như hoa.
The little girl smiles like a flower.
Illustration or Example (such as, for example): To introduce a list of examples or to clarify a general statement.
Structure: Noun + như + [list of items].
Examples:
Tôi thích các môn thể thao như bóng đá và bơi lội.
I like sports such as football and swimming.
Một số thành phố lớn như Hà Nội và Thành phố Hồ Chí Minh có nhiều di tích lịch sử.
Some big cities like Hanoi and Ho Chi Minh City have many historical sites.
Manner or Condition (as if, as though): Often paired with là to express a hypothetical or perceived manner.
Structure: ...như (là) + clause.
Example:
Cô ấy nhìn tôi như là chưa từng gặp bao giờ.
She looked at me as if she had never met me before.
Conformity (as per, as already): To indicate adherence to a previous statement or established practice.
Example:
Xin vui lòng hoàn thành công việc như đã hẹn.
Please complete the work as agreed.
Example Pairs
Observe how the choice between bằng and như changes the meaning, even in seemingly similar contexts.

Học tiếng Việt cũng khó như học tiếng Anh.
Learning Vietnamese is also as difficult as learning English. (Note: Here 'như' is also used for comparison of equality for 'as...as' when preceding an adjective, but 'bằng' is typically more direct for quantifiable equality. This showcases a subtle overlap where 'như' can imply comparison of quality/difficulty, sometimes interchangeable, but 'bằng' is safer for measurable equality.)
Học tiếng Việt cũng khó bằng học tiếng Anh.
Learning Vietnamese is also as difficult as learning English.

Common Patterns
Some expressions are fixed and typically use only one of the two words.
bằng cách: (by way of, by doing X) – Specifies the method.
Họ tiết kiệm tiền bằng cách cắt giảm chi tiêu.
They save money by cutting expenses.
bằng mọi giá: (at all costs, no matter what) – Emphasizes determination.
Tôi sẽ hoàn thành dự án này bằng mọi giá.
I will finish this project at all costs.
bằng lòng: (to agree, to be satisfied/content) – An idiomatic expression.
Cô ấy đã bằng lòng với quyết định đó.
She agreed with that decision.
như vậy/thế: (like that, in that way) – Refers to a manner or state previously mentioned or understood.
Đừng làm ồn như vậy nữa.
Don't make noise like that anymore.
như là: (as if, such as) – Can introduce hypothetical situations or examples. In example lists, it's often interchangeable with just như, but như là can add emphasis or a sense of 'as if'.
Anh ấy nói như là chuyện đó đã xảy ra rồi.
He speaks as if that had already happened.
như thường lệ: (as usual, as always) – Indicates a customary action or state.
Anh ấy đến muộn như thường lệ.
He arrived late as usual.

Common Mistakes
Mistake 1 — Using như for equality/measurement.
Learners often confuse 'as...as' constructions, incorrectly using như where bằng is required for an explicit statement of equality or equal measure.
❌ Chiếc xe này nhanh như chiếc xe kia.
✅ Chiếc xe này nhanh bằng chiếc xe kia.
The mistake is using như to express that two cars have the same speed. While như can imply similarity, for direct measurement or comparison of degree ('as fast as'), bằng is the correct choice.
Mistake 2 — Using bằng for simple resemblance or illustration.
Conversely, using bằng when simply describing a similarity or giving an example is incorrect, as bằng does not carry the meaning of 'similar to' in this context.
❌ Các loại rau bằng cà chua, cải bắp đều tốt cho sức khỏe.
✅ Các loại rau như cà chua, cải bắp đều tốt cho sức khỏe.
The mistake here is using bằng to introduce examples of vegetables. Bằng is for means or equality, not for 'such as'. Như is used to list examples.
Mistake 3 — Confusing means with manner.
While both can relate to 'how' an action is performed, bằng specifies the concrete instrument or method, whereas như describes the abstract manner or resemblance of the action.
❌ Anh ấy viết thư như bút chì.
✅ Anh ấy viết thư bằng bút chì.
The mistake implies that "he writes letters like a pencil" which is nonsensical. Bằng is needed to state the tool (pencil) used for writing. If you wanted to say "He writes like an artist," you would use như (Anh ấy viết như một nghệ sĩ) to describe the manner.
