Answer: -x^10y^15m^5
Step-by-step explanation:
The term -x^2 is the same as -1*x^2
Raising -1 to an odd number power leads to -1. So this is why the answer has the negative out front.
For each of the variable terms, multiply the inner and outer exponents. For example, (x^2)^5 = x^(2*5) = x^10.
The general rule is (a^b)^c = a^(b*c).
For the term 'm', think of it as m^1
