(0.66)(power 3) - (0.1)(power 3)/ (0.66)(power 2) + 0.066 + (0.1)(power 2) is:
Choices.
A) 0.86  B) 0.56  C) 0.96  D) 0.69  E) 0.76

Rationale: "given expression = ( 0.66 ) ( power 3 ) - ( 0.1 ) ( power 3 ) / ( 0.66 ) ( power 2 ) + ( 0.66 x 0.1 ) + ( 0.1 ) ( power 2 ) = a ( power 3 ) - b ( power 3 ) / a ( power 2 ) + ab + b ( power 2 ) = ( a - b ) = ( 0.66 - 0.1 ) = 0.56 answer is b"
Answer: B
