Select the correct combination of mathematical signs that can sequentially replace the * signs and balance the equation.
512 * 32 * 9 * 100 * 6 * 25 * 2
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. ÷, ×, −, +, =, ×.
Given equation: 512 * 32 * 9 * 100 * 6 * 25 * 2
Let us check all the options:
Option 1: ÷, ×, +, =, −, ×
The expression becomes:
= 512 ÷ 32 × 9 + 100 = 6 - 25 × 2
= 244 is not equal to -44.
Option 2: ÷, ×, +, −, =, ×
= 512 ÷ 32 × 9 + 100 - 6 = 25 × 2
= 238 is equal to 50.
Option 3: ÷, ×, −, +, =, ×
= 512 ÷ 32 × 9 - 100 + 6 = 25 × 2
= 50 is not equal to 50.
Hence, option 3 is the correct answer.
