Simplify: (0.75 * 0.75 * 0.75 – 0.25 * 0.25 * 0.25) / (0.75 * 0.75 + 0.75 * 0.25 + 0.25 * 0.25).

Topic: Simplification
Subtopic: Algebraic Identities

A0.25

B0.50

C0.75

D1.00

Explanation

Expression is (a^3 – b^3) / (a^2 + ab + b^2) = a – b. Here a = 0.75, b = 0.25. Result = 0.75 – 0.25 = 0.50.
