Best ResponseYou've already chosen the best response.2Start 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.

Best ResponseYou've already chosen the best response.2Don't multiply exponents. In this case you need to add them.

Best ResponseYou've already chosen the best response.2I 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

Best ResponseYou've already chosen the best response.2Now 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.

Best ResponseYou've already chosen the best response.2Now we have this, right? dw:1440126329963:dw

Best ResponseYou've already chosen the best response.1Yes so then my next step would be to add the a on top with the a on bottom???

Best ResponseYou've already chosen the best response.2Now we move the a with the negative exponent from the numerator to the denominator by making the exponent positive.

Best ResponseYou've already chosen the best response.2We 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.

Best ResponseYou've already chosen the best response.2We 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.

Best ResponseYou've already chosen the best response.1Yeah. so now do we multiply the 4 and the 6 or add

Best ResponseYou've already chosen the best response.2When you raise a fraction to a power, raise the numerator to the power and raise the denominator to the power.

Best ResponseYou've already chosen the best response.2In the numerator, you need to raise a power to a power, so multiply the exponents.

Best ResponseYou've already chosen the best response.2In the denominator, we are raising a product to a power, so we raise each factor to that power.
