simplify this equation: y7z5/yz4
Any time you have an exponents problem, you look at whether the base is the same and if you are multiplying or dividing (or using parentheses). With multiplying, you would add the exponents; using parentheses, you would multiply the exponents; lastly, with division you subtract the exponents. In this case, our exponents on the y are 7 and 1, but we divide, so we end up with y6 and with z, we have 5 and 4, so we end up with just z. Therefore, our final answer would be y6z.
y7z7 / yz4
y7-1 * z7-4
