<em>Step one first you are going to apply the exponent rule so from each number take the exponents and line up the equation to look like this. 4^3-5 so 3-5=-2</em>
<em>Step two Rewrite the equation to look like this 4^-2 now we simplified the exponents lets do the next step. Now we are going to apply the exponent rule again to change 4^-2 to a positive number=1/4^2</em>
<em>Step three. This is the solving step for our final answer. 1/4^2 we are going to solve 4 squared. 4^2=16 because the exponent means how many times we multiply by 4. so 4x4=16. </em>
