M = (2 - 1 / 2) (2 - 1 / 2) + ( - 1) * {2 - [3 / 2÷(2 + 1 / 4)]} + √25 / 4 - 4 ?
M = (2 - 1 / 2) (2 - 1 / 2) + ( - 1) * {2 - [3 / 2÷(2 + 1 / 4)]} + √25 / 4 - 4 .
M = (2 - 1 / 2) (2 - 1 / 2) + ( - 1) * {2 - [3 / 2÷(2 + 1 / 4)]} + √25 / 4 - 4 .
En resumen
M = (3 / 2)(3 / 2) + ( - 1)x{2 - (3 / 2÷(9 / 4))} + 5 / 2 - 4 M = 9 / 4 + ( - 1){2 - 2 / 3} - 3 / 2 M = 9 / 4 + ( - 1)(4 / 3) - 3 / 2 M = 9 / 4 - 4 / 3 - 3 / 2 M = - 7 / 12.
M = (3 / 2)(3 / 2) + ( - 1)x{2 - (3 / 2÷(9 / 4))} + 5 / 2 - 4
M = 9 / 4 + ( - 1){2 - 2 / 3} - 3 / 2
M = 9 / 4 + ( - 1)(4 / 3) - 3 / 2
M = 9 / 4 - 4 / 3 - 3 / 2
M = - 7 / 12.
