1. Nnesha

when we multiply same bases we should ADD their exponents $\huge\rm x^m \times x^n=x^{m+n}$

2. narissa

16^8

3. Nnesha

no , base would stay the same and no it's not 8 remember one of the exponent is negative 3+(-5)

4. narissa

4^-2

5. anonymous

6. Nnesha

yes right now flip the fraction to make the positive exponent $\huge\rm x^{-m} =\frac{ 1 }{ x^m }$

7. narissa

im confused

8. narissa

I/4^2

9. Nnesha

alright here is an example $\huge\rm \frac{ x^{-m} }{ 1 }=\frac{ 1 }{ x^m}$ flip the fraction and change the sign of the exponent

10. Nnesha

yes that's right
