use identity a^3 +b^3 = (a+b) (a^2 - ab + b^ 2)
a = 0.87 and b= 0.13
then answer is
(0.87 + 0.13) (0.87^ 2 - 0.87 × 0.13 + 0.13^2)÷ (0.87 ^2 - 0.87 × 0.13 + 0.13 ^2)
= (0.87+ 0.13)
= 1 and.
a = 0.87 and b= 0.13
then answer is
(0.87 + 0.13) (0.87^ 2 - 0.87 × 0.13 + 0.13^2)÷ (0.87 ^2 - 0.87 × 0.13 + 0.13 ^2)
= (0.87+ 0.13)
= 1 and.
