Question

Para A= (3elevado a 2 .4elevado a -2) e B= (1/3+1/2)elevado a -3 , Calcule A elevado a -2 ÷ B

Answer 1

A=
3^2.4^-2=
9.(1/4)^2=
9.1/16=
9/16

B=
(1/3+1/2)^-3=
(2.1/6+3.1/6)^-3=
(2/6+3/6)^-3=
(5/6)^-3=
(6/5)^3=
216/125

A^-2:B
(9/16)^-2:216/125=
(16/9)^2:216/125=
256/81:216/125=
256/81.125/216=
32000/17496=
4000/2187
