Select the correct combination of mathematical signs to replace the * signs and to balance the given equation.
√(729 * 9) * 67 * 81 * (4 * 6) * 19
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. ÷, +, =, −, ×, +.
Given equation: √(729 * 9) * 67 * 81 * (4 * 6) * 19
Option 1: ÷, +, =, −, ×, +
After interchanging the expression becomes:
= √(729 ÷ 9) + 67 = 81 − (4 × 6) + 19
= √81 + 67 = 81 − 24 + 19
= 9 + 67 = 81 − 24 + 19
= 76 = 76
= 76 is equal to 76.
As we have found our answer, there is no need to check further options.
Hence, option 1 is the correct answer.
