(0.8)(power 3) - (0.5)(power 3)/ (0.8)(power 2) + 0.40 + (0.5)(power 2) is: Choose the correct choice from the following choices.
A) 0.6	B) 0.5	C) 0.35	D) 0.3	E) None of them
Given expression   = (0.8) (power 3) - (0.5)(power 3) / (0.8)(power 2) + (0.8 x 0.5) + (0.5)(power 2)   = a (power 3) - b(power 3) / a(power 2) + ab + b(power 2)   = (a - b)   = (0.8- 0.5)=
