Evaluate 1/2a^–4b^2 for a= –2 and b= 4.
What exponent follows the "a^" ?
You need to use some parentheses to clarify what the exponents are. Also, is (1/2) at the beginning a multiplying coefficient or is the following a in part of the denominator?
the exponet for a^ is -4. And 1/2 is the beginning of the problem.
