    Start with this: Combine a's together, and combine b's together in the denominator. When you multiply powers with the same base, add the exponents.

    Is that right or not

    Don't multiply exponents. In this case you need to add them.

    I put the a's together and the b's together to make it easier to understand which exponents need to be added together. |dw:1440126038498:dw|

    Now here is the next step. A negative exponent in the numerator is a positive exponent in the denominator. A negative exponent in the denominator is a positive exponent in the numerator.

    Yes so then my next step would be to add the a on top with the a on bottom???

    Now we move the a with the negative exponent from the numerator to the denominator by making the exponent positive.

    We moved the a with the negative exponent in the numerator to the denominator by making the exponent positive. Once we had a^4 in the denominator, we were able to multiply it by a^8 to get a^12 in the denominator.

    We still have a negative exponent. It's the b^-6 in the denominator. We move b^-6 to the numerator by making the exponent positive.

    Yeah. so now do we multiply the 4 and the 6 or add

    When you raise a fraction to a power, raise the numerator to the power and raise the denominator to the power.

    In the numerator, you need to raise a power to a power, so multiply the exponents.

    In the denominator, we are raising a product to a power, so we raise each factor to that power.
