## anonymous one year ago Help with negative exponents?

1. anonymous

Do you know what negative exponents are

2. anonymous

yes

3. anonymous

What do you need help with

4. anonymous

$\huge b^{-n}=\frac{1}{b^n}$ no matter if $$n$$ is positive or negative

5. anonymous

How to solve them, so like if there is a oriblem like 7^-2

6. anonymous

okay

7. phi

$7^{-2}$ is not "solved", but it can be changed to a different form for example, if you "flip" it (and change the -2 to +2), it can be written as $\frac{1}{7^2}$ you could also write it as $\frac{1}{49}$
