Answer: Chris made a mistake in step 2 -C

Answer 2

C: Chris made a mistake in step 2.

Explanation:

There are 4 main exponent rules in mathematics. In step 1, Chris followed the correct rule of:

`(a^(x))(a^(y))=a^(x+y)`

However, in step 2, he messed up. The correct rule is:

`(a^(x))^(y)=a^((x)(y))`

This means that step 2 should have been
`4^(-15)`

Hope this helps! :^)
