Simplify: (0.87 * 0.87 * 0.87 + 0.13 * 0.13 * 0.13) / (0.87 * 0.87 – 0.87 * 0.13 + 0.13 * 0.13).

Topic: Simplification
Subtopic: Algebraic Identities

A0.74

B0.87

C1.00

D1.13

Explanation

Expression is of form (a^3 + b^3) / (a^2 – ab + b^2) = a + b. Here a = 0.87, b = 0.13. Sum = 0.87 + 0.13 = 1.00.
