Tyler simplified the expression. His procedure is shown below.

Answer:
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.
Answer:
B:Both powers should be in the denominator with positive exponents.
Step-by-step explanation:
We are given that Tyler simplified an expression
[tex]x^{-3}y^{-9}[/tex]
We have to find an error which Tyler makes in her simplification
Step 1: [tex]x^{-3}y^{-9}[/tex]
Step 2:[tex]\frac{1}{x^3}\cdot y^{-9}[/tex]
Step 3:[tex]\frac{1}{x^3y^9}[/tex]
Hence, Tyler's error is both exponents should be denominator with positive exponents.
Answer:B:Both powers should be in the denominator with positive exponents.
