Question

encuentra el resultado de las siguientes operaciones

3 [8(-2+4)-5(7-9)]+5 [(4-8)6]

Answer 1

3 [8 (-2+4) -5 (7-9)] + 5 [(4-8)6]
3 [ 8 (2) -5 (-2)] + 5 [(-4)6]
3 [ 16 + 10 ] + 5 [ -24]
3[26] -120
78 - 120 = -42

Answer 2

3 [8 (-2+4) -5 (7-9)] +5 [(4-8)6]
= 3 [8 (2) -5 (-2)] +5 [(-4) 6]
= 3 [16+10] +5 [-24]
= 3 [26] +5 [-24]
= 78 - 120
= -42
