Answer 1

missing file: 4(x-y)^4

since they give you the values of x and y, simply plug these into the expression and evaluate.

4(-2-(-4))^4

parentheses first. distribute inside the parentheses to get 4(-2 + 4)^4, then simplify -2 + 4. apply the exponent (the exponent only applies to the expression inside the parentheses). finally, multiply the result by 4.
