Answer»

FOLLOW BODMAS rule to solve this question, as per the order given below,

Step-1: Parts of an equation ENCLOSED in the ‘BRACKETS’ must be solved first

Step-2: Any mathematical ‘OF’ or ‘EXPONEMTS’ must be solved next

Step-3: Next the PART of the equation that contains ‘DIVISION; and ‘MULTIPLICATION’ are calculated

Step-4: Last but not least, the parts of the equation that contains ‘ADDITION’ and ‘SUBTRACTION’ should be calculated

Now, the given expression:

⇒ ?2 + √1024 = 561

⇒ ?2 + 32 = 561

⇒ ?2 = 561 – 32

⇒ ?2 = 529

⇒ ?2 = (23)2

⇒ ? = 23
