Question

resuelve las siguientes operaciones combinadas a)-5×3+8-(4-1×5) b)-12×[-6-10x(-2-3)] c)-3(4-2+5) d)-15(-4)+2[-3(2)+(6-2(8))]​

Answer 1

Explicación paso a paso:

a) -5×3+8-(4-1×5)

= - 15 + 8 - (4 - 5)

= - 7 - 4 + 5

= - 11 + 5 = - 6

b) -12×[-6-10x(-2-3)]

= - 12 x [- 6 - 10 x (-5)]

= - 12 x [-6 + 50]

= - 12 x [44] = - 528

c) -3(4-2+5)

= -3 (7)

= - 21

d) -15(-4)+2[-3(2)+(6-2(8))]​

= 60 + 2 [-6 + (6 - 16)]​

= 60 + 2 [-6 + (-10)]​

= 60 + 2 [-6 - 10]​

= 60 + 2 [-16]​

= 60 - 32 = 28
