What is the answer to x^7:x^-4

you subtract the powers when dividing

therefore 7 - (-4)

=7+4

=11

=x^11

So, when you are dividing powers, you can bring the denominator to the numerator and change the sign of the exponent. Then you can use power rules to find the result. Here the power of the exponent is just 7+4=11.

That's it!
