Which two numbers, from among the given options, should be interchanged to make the given equation correct?
(6)3 ÷ 12 + [(√81) × 4] - (28 ÷ 2) + 24 = 43
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 12 and 24.
Given equation: (6)3 ÷ 12 + [(√81) × 4] - (28 ÷ 2) + 24 = 43
Option 1: 12 and 24
After interchanging the expression becomes:
(6)3 ÷ 24 + [(√81) × 4] - (28 ÷ 2) + 12 = 43
216 ÷ 24 + [(9) × 4] - (14) + 12 = 43
216 ÷ 24 + 36 - (14) + 12 = 43
9 + 36 - 14 + 12 = 43
43 = 43
