#1) any number, variable etc. to the 0 power will always be 1 so x to the 0 power is 1. add the y values on both sides so y to the the 7 power and y to the 3 power should be added 7+3 = 10 so it would now be y to the 10th power. for the 9 it would be multiplied by the number on the other side and there is no number standing on its own we would multiply it by 1. the final answer would be 9y^10
#2) let’s start off with the numbers. multiply 10•7•8 to get 560. then we will add all the U powers so that would be 7+9 = 16 making it u^16. lastly we should add all the v powers so it would 3+8+4 = 15 so ur final answer would be 560u^16v^15.
