So I need help. I have a quiz tomorrow, and don't know what to do! So, it's 5 to the 7 th power over 5 to the 4 th power. So 5^7/5^4 and I dont know how to solve it

To solve it you just multiply the # by how many powers it has like 5×5×5×5×5×5×5 for the first problem and 5×5×5×5 for the second problem
