Math Problem Statement

Work out 3 × (1 + 2^2)^2

Solution

The problem presented in the image is:

3×(1+22)23 \times (1 + 2^2)^2

Let's break it down step by step:

  1. Evaluate the exponentiation inside the parentheses: 22=42^2 = 4

    Now the expression becomes: 3×(1+4)23 \times (1 + 4)^2

  2. Simplify the addition inside the parentheses: 1+4=51 + 4 = 5

    So now the expression becomes: 3×523 \times 5^2

  3. Evaluate the exponent: 52=255^2 = 25

  4. Multiply: 3×25=753 \times 25 = 75

Thus, the final answer is:

75\boxed{75}
