## anonymous 5 years ago 2^-3 need help with this problem and also 10x^8/5x^-14 (integer exponents and scientific notations)

1. anonymous

Just remember that when you multiply exponents with the same base you add their exponents. When you divide you subtract $a^b \times a^c = a^{b+c}$ $\frac{a^b}{a^c} = a^{b-c}$

Does that help?

3. anonymous

what do u mean by the same base?

4. anonymous

Well, in the above example I gave, the base is a. It's the thing you are raising to a power.
