(-5xyz^4)^2

Question

(-5xyz^4)^2

Answer 1

Hello, Nick

Well, it will be 25

then x^2

y^2

(z^4)^2 = z^8 when you raise a power to a power, we need to multiply the exponents. 

If you don't see an exponent, it is one.. Thus, x^2. 2 times 1 equals two.

Answer 2

-5 times x times y times z times z times z times z times -5 times x times y times z times z times z times z.

Does that help? Count up the xs, ys and zs. And don't forget the -5 times -5.
