Which two numbers, from among the given options, should be interchanged to make the given equation correct?
54 - (3 × 12) ÷ (8)1/3 + (11 × 4) + 6 = 69
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 3 and 4.
Given equation: 54 - (3 × 12) ÷ (8)1/3 + (11 × 4) + 6 = 69
Option 1: 3 and 4
After interchanging the expression becomes:
54 - (4 × 12) ÷ (8)1/3 + (11 × 3) + 6 = 69
54 - 48 ÷ 2 + 33 + 6 = 69
54 - 24 + 33 + 6 = 69
69 = 69
