Logarithm help needed

Mathematics
1 answer:
sashaice [31]3 years ago
4 0

Answer:

See below.

Step-by-step explanation:

Helen made a mistake in the last step.

2^(4/3) / e = (∛(2^4) / e  = ∛(16) / e .

It is the cube root of  2^4 not the 4th root of 2^3.

Stephen made a mistake in the first step.

He replaced ln2 by 2 which is evidently wrong (e^ln2 = 2  NOT ln 2).
