Help? #7 I did it but the answer was wrong...I have the answers I need explanation

Answer 1

7.

`(3^4x^4)/(3x^2) = 3^(4 - 1)x^(4 - 2) = 3^3x^2 = 27x^2`

10.

`((-2)^5 * (-3)^4 * (-5)^3)/((-2)^3 * (-3) * (-5)^2) =`

`= ((-2)^5 * (-3)^4 * (-5)^3)/((-2)^3 * (-3)^1 * (-5)^2)`

`= (-2)^(5-3) * (-3)^(4-1) * (-5)^(3-2)`

`= (-2)^(2) * (-3)^(3) * (-5)^(1)`

`= (-2) * (-2) * (-3) * -3 * (-3) * (-5)`

`= 4 * (-27) * (-5)`

`= 540`
