Answer
-25
Work Step by Step
7 – 2(9- 11)$(-2)^{3}$
Step 1: Work inside Parentheses: (9 -11) = -2
7 – 2(-2) $(-2)^{3}$
Step 2: Apply the exponent: $(-2)^{3}$
is -2 * -2 * -2 = -8
7 – 2(-2)(-8)
Step 3 : Multiply from left to right : 2 *(-2) =(-4)
7 –(-4)(-8)
Multiply (-4)(-8) = 32
7- (+32)
Step 4: Change subtraction to addition
7 + (-32) = -25
