Question

Simplify (0.5 x 0.05 x 0.05 - 0.04 x 0.04 x 0.04) / (0.05 x 0.05 + 0.002 + 0.04 x 0.04)=

• A. 1
• B. 0.1
• C. 0.01
• D. 0.001

Answer 1

Answer:

C. 0.01

(0.5 x 0.05 x 0.05 - 0.04 x 0.04 x 0.04) / (0.05 x 0.05 + 0.002 + 0.04 x 0.04)= (0.05)³ - (0.04)³ /(0.05)² + 0.05 x 0.04 + (0.04)² = 0.05 - 0.04 = 0.01
