Answer 2

Given :- x = 0.28

To Find :-

• x³

Solution :-

→ x = 0.28

→ x = (0.20 + 0.08)

cubing both sides,

→ x³ = (0.20 + 0.08)³

using (a + b)³ = a³ + b³ + 3ab(a +b) in RHS,

→ x³ = (0.20)³ + (0.08)³ + 3 * (0.20) * (0.08)(0.20 + 0.08)

→ x³ = 0.008 + 0.000512 + 0.048 * 0.28

→ x³ = 0.008 + 0.000512 + 0.01344

→ x³ = 0.021952 (Ans.)
