Question

se a = (1/2 -3/4)-² e b = (3/4-1/2)² então o valor da razão de 16 b/a é:

Answer 1

a= ( 4-6/8)^2 = (-2/8)^2 (-1/4) ^2 =  1/16

b= (6-4/8) ^2 = (2/8)^2 = (1/4)^2= 1/16

16. 1/16/1/16 = 16. 1/16 . 16/1 = 16 . 16/16 = 16.1= 16

Answer 2

Olá Cacau

a = (2/4 - 3/4)^-2 = (-1/4)^-2 = (-4)^2 = 16

b = (3/4 - 2/4)^2 = (1/4)^2 = 1/16

16b/a = (16/16)/16 = 1/16
