Evaluate means to substitute the given values into where they are in the given expression. In this case, you are given the expression 1/2a^-4b^2, and you are given that a = -2 and b = -4. You would substitute -2 for a in the expression and -4 for b. Once you do that, I assume you can find the answer. Get it?

What about the exponents? Don't they come first?

anonymous · Answer

No. Substitute the values in and put them in parentheses, then solve with the exponents.
