Question

Qual é o valor de $a^{b}$, sendo a = $\frac{2 . ( \frac{1}{3} ) - 2^{2} }{( \frac{1}{2})^{-2} }$ e b=$\frac{- \frac{5}{4} -( \frac{1}{2} )^{2} }{ \frac{2}{3}^{-1} }$

a = (2/3 - 4)/(1/2 - 2)  

(2 - 12/3 = -10/3

1/2 - 2 = 1/2 - 4/2 = -3/2

a = (-10/3)/(-3/2) = (10/3)*(2/3) = 20/9 

b = (-5/4 - 1/4)/(2/3 - 3/3) = ((-6/4)/(-1/3) = (6/4)*/3/1) = 18/4 = 9/2

a^b = (20/9)^(9/2) = 36.35
