Question

Qual e o valor de a sobre b, sendo a =(1/4)-² + (1/3)-² e b 2.(1/3)-¹ -2² / (1/2)-²

Answer 1

Por gentileza, verifique se os valores de "a" e "b" estão corretos.

$a = (\cfrac{1}{4} )^{-2} + (\cfrac{1}{3} )^{-2}\\\\a = (\cfrac{4}{1} )^{2} + (\cfrac{3}{1} )^{2}\\\\a = 16 + 9\\a = 25\\\\b = 2 \cdot (\cfrac{1}{3} )^{-1}\\\\b = 2 \cdot \cfrac{3}{1}\\\\b = 6$

$\cfrac{a}{b} = \cfrac{25}{6}$
