Tyler simplified the expression. his procedure is shown below.

Step-by-step explanation:

                                                        1

Tyler correctly rewrote x^(-3) as , but

                                                       x³

                                                       1

he incorrectly wrote y^(-9) as  

                                                    y^(-9)

Both x^9 and y^9 should be in the denominator.  This corresponds to the 2nd given possible answer.

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.

im sorry but no. i just need to answer for 50 poonts oof

add a pic of the graph, then ill edit this "answer" and solve it for you : 3
