Question

Find the value of root 2 + root 5 / root 5 if root 5 = 2.236 and root 10 = 3.162

Answer 1

$\frac{\sqrt{2}+\sqrt{5}}{ \sqrt{5} }=\frac{(\sqrt{2}+ \sqrt{5})\sqrt5}{\sqrt{5}\sqrt5}=\frac{\sqrt{2\cdot5}+5}5=\frac{\sqrt10}{5}+1\approx\frac{3.162}{5}+1=1,6324$

Answer 2

Answer: √2+√5/√5 ×√5/√5=√10+5/5

=√10/5+5/5 √10/5+1

=3.162/5+1

=0.6324+1

=1.6324
