Help me you kings and queens

Answer 1

When you have a negative exponent, you move the base with the negative exponent to the other side of the fraction to make the exponent positive.

For example:

$x^{-3}$ or $\frac{x^{-3}}{1} =\frac{1}{x^3}$

$\frac{1}{y^{-2}} =\frac{y^2}{1}$ or $y^2$

$2^{-3}=\frac{1}{2^3} =\frac{1}{8}$

#1:  $2^5=2*2*2*2*2=32$

#2.  $2^{-4}$   Make the exponent positive   $\frac{1}{2^4} =\frac{1}{2*2*2*2} =\frac{1}{16}$

#3:  $5^{-2}$    Make the exponent positive  $\frac{1}{5^2} =\frac{1}{5*5} =\frac{1}{25}$

#4.  $5^3=5*5*5=125$
