Answer:
Step-by-step explanation:
We perform arithmetic in this order. In the second expression (-3)^2, we use the bracketed number first which is -3 and then raise it to the power of 2: (-3)*(-3) = 9.
In the first expression, remember that exponentiation is just extended multiplication. So all we’re doing here is the Multiplication part. We have a -1 in the front of the number, and then we have 3^2. So this answer will be (-1)*(3^2) = -9.
