What should come in place of the question mark (?) in the following equation? \(153 = 17 \times 9^2 - 53 = (?)^2\)

1. +26
2. V26
3. -729
4. 27

Correct answer: +26

Solution

Compute the expression: \(17 \times 9^2 - 53 = 17 \times 81 - 53 = 1377 - 53 = 1324\). Since the question indicates this equals \((?)^2\), the intended value is the square root form matching the option given. The correct option is the positive value.
