Negative exponents

[gaily1008]

When you have a negative exponent does this mean your answer is negative? For example does

2^-3 = -2*-2*-2=-8?

Thank you!

\(\displaystyle 2^{-3} \ = \ \frac{1}{2^3} \ = \ \frac{1}{8}.\)

Thanks for the help. Have a great day!

Remember this rule (tatoo it to your wrist!):
a^(-p) = 1 / a^p

1 / a^(-p) = a^p
