Question

solve the following by using identity; 0.98 cube ​

Answer 1

(0.98)³ = 0.941192

Step-by-step explanation:

(0.98)³ = (1 - 0.02)³

(a - b)³ = a³ - b³ - 3ab(a - b)

therefore,

(1 - 0.02)³ = (1)³ - (0.02)³ - 3(1)(0.02)(1-0.02)

= 1 - 0.000008 - 0.06(0.98)

= 0.999992 - 0.0588

= 0.941192

Therefore (0.98)³ = 0.941192
