Question:-

$\rm \: evaluate\: \frac{15}{ \sqrt{10} + \sqrt{20} + \sqrt{40} - \sqrt{5} - \sqrt{80} }evevaluat$

$\rm \: it \: begin \: given \: that \: \sqrt{5} = 2.236 \: \: and \: \sqrt{10} = 3.162itbegingiventhat$

Solution:-

$\to \: \rm \: \: \frac{15}{ \sqrt{10} + \sqrt{20} + \sqrt{40} - \sqrt{5} - \sqrt{80} }→$

Now we can write as

$\to \: \rm \: \frac{15}{ \sqrt{10} + 2 \sqrt{5} + 2 \sqrt{10} - \sqrt{5} - 4 \sqrt{5} }→$

$\rm \: \to \: \frac{15}{3 \sqrt{10} - 3 \sqrt{5} }→$

Taking common 3 from denominator

$\rm \: \to \: \frac{ \not15}{ \not3( \sqrt{10} - \sqrt{5} )}→$

We get

$\rm \: \to \: \frac{5}{ \sqrt{10} - \sqrt{5} }→$

Now value are given

$\rm \: \sqrt{10}$ = 3.162

$\rm \: \sqrt{5}$ = 2.236

We get

$\rm \: \frac{5}{3.162 - 2.236}$

$\rm \: \frac{5}{0.926}$
