Question

Root 2=1.414 root 5=2.236 find root 10 minus root 5 by 2

Answer 1

Answer:

0.462852

Step-by-step explanation:

Hi friend!!!

First we will factorise the numerator: $\frac{(\sqrt{5}*\sqrt{2})- \sqrt{5} }{2}$\

Now taking root 5 common : $\frac{\sqrt{5}*(\sqrt{2} - 1 )}{2}$

Substituting the values : 2.236(1.414-1)/2

= (2.236)(0.414)/2

= 0.925704‬/2

= 0.462852

Hope it helps you!!!
