(-1)³+(√2)⁴ ÷ [2 x 1/2 -1/2 -(1/3 -1)²]
-1 +(√2)⁴ ÷ [2 x 1/2 -1/2 -(1/3 -1)²]
-1 +4 ÷ [1 -1/2 -(1/3 -3/3)²]
-1 +4 ÷ [2/2 -1/2 -(-2/3)²]
-1 +4 ÷ [1/2 -(-2/3)²]
-1 +4 ÷ [1/2 -4/9]
-1 +4 ÷ [9/18 -8/18]
-1 +4 ÷ [1/18]
-1 +4 x 18=-1+72=71
Letra A
((-1)³+(â2)^4) / [2(1/2)-(1/2)-((1/3)-1)²]
((-1)+(2¹/²)^4) / [ (1) - (1/2)-((1-3)/3)²]
((-1)+(2²) / [ (1) - (1/2)- (-2/3)²]
((-1)+(2²) / [ (1) - (1/2)- ( +4/9)]
(-1+ 4) / [ 1 - 1/2 - 4/9]
(+3) / ( 18 - 9 - 8) /18
54
(-1)³ + (â2)^4/(2*1/2 - 1/2 - (1/3 - 1)²)) =
-1 + 4/(1 - 1/2 - (1/3 - 3/3)²) =
-1 + 4/(1/2 - 4/9)
mmc = 18
-1 + 4*18/(9 - 8) = -1 + 72 = 71 (A)
pronto
(-1)^3 + (â2)^4 ÷ [ 2x1/2 - 1/2 - (1/3 - 1)^2 ]
-1 + 4 ÷ [ 1 - 1/2 - (-2/3)^2 ]
-1 + 4 ÷ [ 1/2 - 4/9 ]
-1 + 4 ÷ 1/18
-1 + 4 x 18 =
-1 + 72 = 71 ...... A
