What approximate value should come in place of the question mark (?) in the following question? (1.45)4 ÷ (1727.9 ÷ 1000)5 × (0.12 × 10)8 = (1.2)? – 3

What approximate value should come in place of the question mark (?) in the following question? (1.45)4 ÷ (1727.9 ÷ 1000)5 × (0.12 × 10)8 = (1.2)? – 3 Correct Answer 4

Follow BODMAS rule to solve this question, as per the order is 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.

(1.45)⁴ ÷ (1727.9 ÷ 1000)⁵ × (0.12 × 10)⁸ = (1.2)^{? – 3}

⇒ (1.44)⁴ ÷ (1728 ÷ 1000)⁵ × (0.12 × 10)⁸ = (1.2)^{? – 3}

⇒ (1.2)⁸ ÷ (1.2)^{3× 5} × (1.2)⁸ = (1.2)^{? – 3}

⇒ (1.2)^{? – 3} = (1.2)

⇒ ? – 3 = 1
