Question

A student simplified the rational expression using the steps shown.

Answer 1

Answer:

No, the answer is not correct

Step-by-step explanation:

In the second step, the student didn’t use the quotient of powers property correctly. They should have subtracted inside the parentheses instead of dividing. This would have left them with x^(4/5). They should have then multiplied this power by ^(1/2) resulting in x^(4/10) which simplified is x^(2/5) which is the correct answer.

Answer 2

No.

$\frac{x^{6/5*1/2}}{x^{2/5*1/2} }$

$\frac{x^{3/5} }{x^{1/5} }$

$=x^{2/5}$
