Question

Insert parentheses and brackets to make the equation true. (2 + 3 × 4² - 11 × 2 = 270)

a. (2 + (3 × 4²) - (11 × 2) = 270)

b. (2 + [3 × 4²] - 11 × 2 = 270)

c. (2 + 3 × (4² - 11) × 2 = 270)

d. (2 + 3 × 4² - (11 × 2) = 270)

Answer 1

In order to make the equation (2 + 3 × 4² - 11 × 2 = 270) true, the parentheses and brackets need to be inserted correctly.

Step-by-step explanation:

To make the equation (2 + 3 × 4² - 11 × 2 = 270) true, we need to insert parentheses and brackets in the equation.

a. (2 + (3 × 4²) - (11 × 2) = 270)
b. (2 + [3 × 4²] - 11 × 2 = 270)
c. (2 + 3 × (4² - 11) × 2 = 270)
d. (2 + 3 × 4² - (11 × 2) = 270)

In this case, the correct answer is option d, (2 + 3 × 4² - (11 × 2) = 270), as it maintains the correct order of operations.
