Question

Raise to the power: (–0.2xy)4

Answer 1

Since there are parenthesis, you have to distribute the exponent to the whole thing. That ends up as -0.2^4 x^4 y^4. -0.2^4 can be simplified, it’s -0.0016. End answer is
-0.0016 x^4 y^4. The ^ symbols just mean that it’s to the power of four. x^4 = x to the power of four.
