= root 5 / 2 root 5 × 2root5
= 2.236 / 20
= 1.118 / 10
= 0.1118

Answer 2

Answer:

$\frac{1}{2\sqrt5}=0.223$

Step-by-step explanation:

Given : Value $\sqrt5=2.236$

To find : The value of $\frac{1}{2\sqrt5}$

Solution :

First we find $2\sqrt5$

$\sqrt5=2.236$

$2\sqrt5=2\times2.236=4.472$

The value of $\frac{1}{2\sqrt5}$

$\frac{1}{2\sqrt5}=\frac{1}{4.472}$

$\frac{1}{2\sqrt5}=0.223$

So, The value of the expression is $\frac{1}{2\sqrt5}=0.223$
