Find the value of {(.98)3 + (0.02)3 + 3 × 0.98 × 0.02 – 1}

Detailed Solution: Question 10

Given:

 {(.98)3 + (0.02)3 + 3 × 0.98 × 0.02 – 1}

Concept used:

(a + b)3 = a3 + b3 + 3ab(a + b)

Calculation:

{(.98)3 + (0.02)3 + 3 × 0.98 × 0.02 – 1

⇒ [(.98)3 + (0.02)3 + 3 × 0.98 × 0.02(0.98 + 0.02)} – 1]

Now, first term is of the form (a + b)3 where a = .98 and b = 0.02

⇒ (0.98 + 0.02)3 – 1 = 1 – 1 = 0

∴ The value is 0.
