Step-by-step explanation:
Do (4^9)^5 first, when an exponent is in a parenthesis with another exponent outside, you multiply them which makes 4^45. Then we multiply 4^0 but this time we add the exponent because there’s no parentheses, which gives you 4^45.
As a rule , - times - = + and - times + = -

Therefore the correct answer to the question is 2m squared n
