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, (0.1458 ÷ 0.2)1/3 ÷ (102.4 × 10)1/5 × (0.5 × 4)5 + 0.9 = [(9)? + 3] ÷ 10 ⇒ (0.729)1/3 ÷ (1024)1/5 × (2)5 + 0.9 = [(9)? + 3] ÷ 10 ⇒ 0.9 ÷ 4 × 32 + 0.9 = [(9)? + 3] ÷ 10 ⇒ 7.2 + 0.9 = [(9)? + 3] ÷ 10 ⇒ 81 = [(9)? + 3] ∴ ? = -1 |
