Find out the approximate value which should replace the question mark (?) in the following question. (12.17)2 + (4.93)2 × 4.98 – ∛127 – 6018.18 ÷ 5.91 = ?3
Find out the approximate value which should replace the question mark (?) in the following question. (12.17)2 + (4.93)2 × 4.98 – ∛127 – 6018.18 ÷ 5.91 = ?3 Correct Answer -9
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,
(12.17)2 + (4.93)2 × 4.98 - ∛127 – 6018.18 ÷ 5.91 = ?3
Taking approximate values as,
12.17 ≈ 12, 4.93 ≈ 5, 4.98 ≈ 5, ∛127 ≈ ∛125, 6018.18 ≈ 6018, 5.91 ≈ 6
⇒ (12)2 + (5)2 × 5 – ∛125 – 6018 ÷ 6 = ?3
⇒ ?3 = -739
⇒ ? = -9.04 ≈ -9
