Question

Please helpppppp :((

Answer 1

`4^(21)`

Explanation:

Answer 2

`(4^(12))/(4^(-9))\\`

Given 4 = a

From the properties of exponents for the example...

`(a^4)/(a^(-2)) = (a*a*a*a)/((1)/(a^2) ) = (a*a*a*a)*a^2 = a^4 * a^2 = a^(4+2) = a^6`

Therefore, the answer is....

`4^(12)*4^(9) = 4^(12+9) = 4^(21)`
