Timothy evaluated the expression using r = 3

and y = 4

Analyze Timothy's steps. Is he correct? If not, why not?

Yes, he is correct.

3. xy

No, he needed to add the exponents when he

simplified the powers of the same base.

1. (75 x ²y²

2. (3) 34-432

3. (5 (31) (-4)

4. (53) (-16)

No, he needed to multiply 3 and - 1 instead of

creating a positive exponent in a fraction.

No, his value of (-4) should be positive because

an even exponent indicates a positive value.
