Question

−4 [2 (− 2/3÷7/2) − 3] + 2 [3 ( 4/2−8/9) + 6(5 − 7)] − (2 − 4) =

Answer 1

Solución:

−4 [2 (− 2/3÷7/2) − 3] + 2 [3 (4/2 − 8/9) + 6(5 − 7)] − (2 − 4) =
−4 [2 (− 2/3×2/7) − 3] + 2 [3 ((36 − 16)/18) + 6(− 2)] − (− 2) =
−4 [2 (− 4/21) − 3] + 2 [(20/6) − 12] + 2 =
−4 [− 8/21 − 3] + 2 [(20 − 72)/6] + 2 =
−4 [(− 8 − 63)/21] − 52/3 + 2 =
−4 [− 71/21] − 52/3 + 2 =
284/21 − 52/3 + 2 =
284/21 − 364/21 + 42/21 = − 38/21

Answer 2

(((-4)*((2*((((-2)/3)/7)/2))-3))+(2*((3*((4/2)-(8/9)))+(6*(5-7)))))-(2-4)
