Answer 1

Tasha made her mistake in step 4.

Answer 2

Step 4 is the incorrect.

Explanation:

From the table attached,

Step 1. Find a pattern in the table.

Correct

Step 2. Find the value of
`4^(-3)=((1)/(16))((1)/(4))=(1)/(64)`

Correct

Step 3. Find the value of
`4^(-4)=((1)/(64))((1)/(4))=(1)/(256)`

Correct

Step 4. Rewrite the value of
`4^(-4)`

`((1)/(256))=-(1)/(4^(-4) )`

Incorrect.

Because it should be
`((1)/(256))((1)/(4))=(1)/(1024)`
