`root(3)((0.2xx0.2xx0.2+0.04xx0.04xx0.04)/(0.4xx0.4xx0.4+0.08xx0.08xx0.08))`का मान क्‍या है?

Options

A. `0.5`
B. `0.25`
C. `0.75`
D. `0.125`

Answer

A

Explanation

According to the question
`impliesroot(3)((0.2xx0.2xx0.2+0.04xx0.04xx0.04)/(0.4xx0.4xx0.4+0.08xx0.08xx0.08))`
`root(3)((0.008+0.000064)/(0.064+0.000512))`
`impliesroot(3)((0.008064)/(0.64512))impliesroot(3)(8064/64512)`
`impliesroot(3)(1/8)=1/2=0.5`
