Question

$Thevalueof\frac{0.051\times 0.051\times 0.051+0.041\times 0.041\times 0.041}{0.051\times 0.051-(0.051\times 0.041)+0.041\times 0.041}is$

• A. 0.00092
• B. 0.0092
• C. 0.092
• D. 0.92
• E. 0.000092

Answer 1

The correct option is C

0.092

$\frac{0.051\times 0.051\times 0.051+0.041\times 0.041\times 0.041}{0.051\times 0.051-(0.051\times 0.041)+0.041\times 0.041}=\frac{a^3+b^3}{a^2-ab+b^2}=0.092$
