Answer: Chris made a mistake in step 2 -C

Answer:

C: Chris made a mistake in step 2.

Step-by-step explanation:

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

[tex](a^{x})(a^{y})=a^{x+y}[/tex]

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

[tex](a^{x})^{y}=a^{(x)(y)}[/tex]

This means that step 2 should have been [tex]4^{-15}[/tex]

Hope this helps! :^)
