B:Both powers should be in the denominator with positive exponents.

Step-by-step explanation:

We are given that Tyler simplified an expression

We have to find an error which Tyler makes in her simplification

Step 1:

Step 2:

Step 3:

Hence, Tyler's error is both exponents should be denominator with positive exponents.

B:Both powers should be in the denominator with positive exponents.
