We all know that exponents with positive integer power mean multiplying the number by itself as many times as the power is. x%5E4=x%2Ax%2Ax%2Ax. This section discusses more complicated exponents -- negative power and powers that are numeric fractions. Two formulas to remember:

+highlight%28+x%5E%28-n%29+=+1%2F%28x%5En%29+%29, and +highlight%28+x%5E%28m%2Fn%29+=+%28root%28+n%2C+x+%29%29%5Em+%29
