Question

averigua el resultado de las siguientes operaciones :a) 3+2 ×[2× (1-3) -2 ],= b) (7-6×2) :5-2×[1- (1-3)] =,c) 3-[3-3 ×[ 2-2 × (1-4)]],= d) [2-(3-9)] :(-2)+1-[(4+2):(-3)] =

Answer 1

A) 3+2x[2x(1-3)-2]
3+2x[2x(-2)-2]
3+2x[(-4)-2]
3+2x(-6)
3-12=-9

B)(7-6.2)5-2.[1-(1-3)]
(7-12):5-2.[1-(-2)]
-5:5-2(1+2)
-1-2.3
-1-6=-7

C)3-[3-3.[2-2.(1-4)]]
3-[3-3.[2-2.(-3)]]
3-[3-3(2+6)]
3-[3-3.8]
3-[3-24]
3-[-21]
3+21=24
