Hi guys,

the task: Identify the errors a stundent made in the following problems and correct them. Explain your answer.

1. (7x)^1/3 = 1 divided by 7x^3

my answer: it should be = (7x)^1/3 = 7^1/3 x^1/3

Is that right?

2. 2^2 divided by 2^1/4 = 2^2/4 = 2^1/2 = square root of 2

What is wrong? I have an idea, but I am not sure.
