Select the correct combination of mathematical signs to sequentially replace the * signs and to balance the given equation
(120 * 15) * 9 * 4√ 81 * 17 * 28 * 95
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. ÷, ×, +, ×, −, =.
Given equation: (120 * 15) * 9 * 4√ 81 * 17 * 28 * 95
Option 1: ÷, ×, +, ×, −, =
After interchanging the expression becomes:
= (120 ÷ 15) × 9 + 4√ 81 × 17 - 28 = 95
= 8 × 9 + 4√ 81 × 17 - 28
= 72 + 4√ 81 × 17 - 28
= 72 + 3 × 17 - 28
= 72 + 51 - 28
= 95 = 95
As we have found our answer, there is no need to check further options.
Hence, ÷, ×, +, ×, −, = is the correct answer.
