(-2x8y-3)-4OK so we know that the negative sign on the 4 exponent makes EVERYTHING in the brackets flip, so now its 1 over everything. Write that down fir the first step. However, the 4 stays as the exponent of the denominator. It would look like this:1       (-2x⁸y^-3)⁴So now its step-by-step math. We will multiply the exponent 4 to the three values in the brackets (-2, x8, y-3), starting with -2. Use your calculator to multiply -2 by itself four times, you should come out with a 16. NOTE: If a negative integer such as -2 is multiplied by itself using exponents (in this case, 4), remember that if the exponent is odd, the answer will be negative. If the exponent value is an even number, it will come out positive. 1       (16x⁸y^-3)⁴Now we will multiply x8 by the exponent 4. When we multiply exponents, we end up adding the exponents. So 8 + 4 = 12 obviously. Then multiply y-3 by exponent 4. -3 + 4 = 1. You can figure out the final answer on your own from here.
