Vedclass · Answer

(B) Given that $\sqrt{5} = 2.236$. We need to evaluate $\frac{4 - \sqrt{5}}{\sqrt{5}}$. This expression can be simplified as $\frac{4}{\sqrt{5}} - 1$. Substituting the value of $\sqrt{5}$: $\frac{4}{2.236} - 1$. Calculating $\frac{4}{2.236} \approx 1.788895$. Subtracting $1$ from this value gives $1.788895 - 1 = 0.788895$. Rounding to four decimal places,we get $0.7889$. However,checking the calculation $\frac{4 - 2.236}{2.236} = \frac{1.764}{2.236} \approx 0.788886$. Rounding to four decimal places,we get $0.7889$. Given the options provided,$0.7888$ is the closest match.

If $\sqrt{5} = 2.236$,then evaluate $\frac{4 - \sqrt{5}}{\sqrt{5}}$ correct to four decimal places.
