Math Problem Statement

Simplify the expression (-4)^3 / [(-2)^2 ⋅ (-2)^3]

Solution

The expression in the image is:

(4)3[(2)2(2)3]\frac{(-4)^3}{[(-2)^2 \cdot (-2)^3]}

Let's break it down and solve it step by step:

Step 1: Simplify (4)3(-4)^3

(4)3=4×4×4=64(-4)^3 = -4 \times -4 \times -4 = -64

Step 2: Simplify the denominator

  • (2)2=(2)×(2)=4(-2)^2 = (-2) \times (-2) = 4
  • (2)3=(2)×(2)×(2)=8(-2)^3 = (-2) \times (-2) \times (-2) = -8

Now, multiply the two parts of the denominator: 4(8)=324 \cdot (-8) = -32

Step 3: Combine the results

Now, the expression becomes: 6432\frac{-64}{-32}

Simplifying this gives: 6432=2\frac{-64}{-32} = 2

Final Answer:

22
