1.	[(75.81 – 12) ÷ 16] = (?)21). 32). 43). 54). 2
Answer» FOLLOW BODMAS rule to solve this question, as per the order given below, Step-1: Parts of an equation ENCLOSED in 'Brackets' MUST be solved first, and in the BRACKET, Step-2: Any mathematical 'Of' or 'Exponent' must be solved next, Step-3: Next, the parts of the equation that contain 'Division' and 'Multiplication' are calculated, Step-4: Last but not least, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated. Given expression is, [(75.81 – 12) ÷ 16] = (?)² Approximating to the CLOSEST integers ⇒ [(76 – 12) ÷ 16] = ?² ⇒ [64 ÷ 16] = ?² ⇒ x²= 4 ∴ x = 2

Answer»

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

Step-1: Parts of an equation ENCLOSED in 'Brackets' MUST be solved first, and in the BRACKET,

Step-2: Any mathematical 'Of' or 'Exponent' must be solved next,

Step-3: Next, the parts of the equation that contain 'Division' and 'Multiplication' are calculated,

Step-4: Last but not least, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated.

Given expression is,

[(75.81 – 12) ÷ 16] = (?)²

Approximating to the CLOSEST integers

⇒ [(76 – 12) ÷ 16] = ?²

⇒ [64 ÷ 16] = ?²

⇒ x²= 4

∴ x = 2
