How do you solve this topic? Im so confused and I need it for tomorrow! I have a test on it!!! |
Hey if you have a negative fraction in the exponent, you just have to flip the base, then multiply all of the exponents by the fraction. Example: (x^2/y^4)^(-1/2) Step 1: Flip base and change exponent sign (x^2/y^4)^(-1/2) = (y^4/x^2)^(1/2) Step 2: Multiply exponents by outer exponent (y^4/x^2)^(1/2) = (y^2/x^1) = y^2/x To convince yourself that (x^2/y^4)^(-1/2) = y^2/x you can play with the sliders here: |
