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,

(1472.2 ÷ 23.13)1/3 + (71.8 × 2.05)1/2 = (?)1/2

Taking the approximate values,

1472.2 ≈ 1472, 23.13 ≈ 23, 71.8 ≈ 72, 2.05 ≈ 2

⇒ (1472 ÷ 23)1/3 + (72 × 2)1/2 = (?)1/2

⇒ (64)1/3 + (144)1/2 = (?)1/2

⇒ 4 + 12 = (?)2

∴ ? = 4
