Question

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.
