Question

Your friend simplifies the expression. Is your friend correct?

( i didnt mean to click yes )

Answer 1

Answer: No

Reason:

The friend should have multiplied the exponents.

This is what the steps should look like:

`(r^6)^4 = r^(6*4)\\\mbox{ \ \ \ \ \ \ } =r^(24)`

The reason for the multiplication is because we have four copies of
`r^4` added together. Repeated addition can be shortened to multiplication.

In other words,

`(r^6)^4 = (r^6)*(r^6)*(r^6)*(r^6) = r^(6+6+6+6) = r^(6*4) = r^(24)`
