The expression = \(\frac{[120×120×120-100×100×100]}{[120×120+120×100+100×100]}\)
Formula used:
a3 - b3 = (a - b) × (a2 + ab + b2)
Calculation:
According to the question
⇒ \(\frac{[120×120×120-100×100×100]}{[120×120+120×100+100×100]}\)
⇒ \(\frac{[120^3-100^3]}{[120^2+120×100+100^2]}\)
⇒ \(\frac{[120-100]\ \times [120^2+120×100+100^2] }{[120^2+120×100+100^2]}\)
⇒ 120 -100 = 20
∴ The required result will be 20.
