Answer:
Step 4
Step-by-step explanation:
Tasha was correct in all the steps leading up to the fourth one. However, in the fourth step was where she messed up.
She said that: [tex]\frac{1}{256} =-\frac{1}{4^{-4}}=4^{-4}[/tex]
However, when we have a negative exponent, in order to get rid of the negative, we simply take the reciprocal of the number and then make the exponent positive. Here, the answer should be:
[tex]\frac{1}{256} =\frac{1}{4^{4}}=4^{-4}[/tex]
