Question

-9+(-5)3)+6+(-4) -10+(+3)4)-12+(+7) -68+(-17)+28

Answer 1

1) -9+(-5³)+6+(-4) = -9+(-125)+2 = -134+2 = -132

2) -10+3⁴-12+7 =  -10+81-5 = -10+76 = 66

3) -68+(-17)+28 = -85+28 = -57

Answer 2

-9+(-15)+6-4-10+12-12+7-68-17+28=-9-15+6-4-10+12-12+7-68-17+28=-82

Answer 3

Let's simplify the expression step by step:

1. -9 + (-5 * 3) + 6 + (-4) - 10 + (3 * 4) - 12 + (7) - 68 + (-17) + 28

2. -9 + (-15) + 6 + (-4) - 10 + 12 - 12 + 7 - 68 - 17 + 28

3. (-9 - 15 + 6 - 4 - 10 + 12 - 12 + 7 - 68 - 17 + 28)

Now, combine the like terms:

-9 - 15 + 6 - 4 - 10 + 12 - 12 + 7 - 68 - 17 + 28 = -122

So, the simplified expression is -122.
