{(.98)3 + (0.02)3 + 3 × 0.98 × 0.02 – 1}
অনুসৃত ধারণা:
⇒ (a + b)3 = a3 + b3 + 3ab(a + b)
গণনা:
{(.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]
এখন, প্রথম পদটি (a + b)3 আকারে রয়েছে যেখানে a = .98 এবং b = 0.02
⇒ (0.98 + 0.02)3 – 1 = 1 – 1 = 0
∴ নির্ণেয় মান হল 0
