Answer 2

Giventhat

=2.236and

10

=3.162

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

Now we can write as

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

\rm \: \to \: \dfrac{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 \: \dfrac{5}{ \sqrt{10} - \sqrt{5} }→

Now value are given

\rm \to \sqrt{10} = 3.162→

10

=3.162

\rm \to \sqrt{5} = 2.236→

5

=2.236

We get

\rm \to \dfrac{5}{3.162 - 2.236}→

3.162−2.236

5

\rm \to \dfrac{5}{0.926}→

0.926

Answer:-

\rm \to 5.399→5.399
