Answer:
9
Explanation:
Anything to the 0th power is equal to 1, so that means that the y with the exponent of 0 = 1. Now 7 multiplied by 1 is just 7, so you can rewrite your problem.
15 - 7 + 1
Solve from left to right combining like terms. Subtract 7 from 15.
8 + 1
8 added to 1 is 9, so the final answer is 9.
