0,5.√(0,09)-2.√(0,05)+\sqrt (1)/(4)

Question

0,5.
`√(0,09)`-2.
`√(0,05)`+
`\sqrt (1)/(4)`

Answer 1

0.21

Explanation:

The given expression is :

`0.5* √(0.09)-2√(0.05)+\sqrt (1)/(4)`

We need to solve it.

We know that,

`√(0.09)=0.3\ and\ √(0.05)=0.223`

So,

`0.5* √(0.09)-2√(0.05)+\sqrt (1)/(4)=0.5* 0.3-2* 0.22+0.5\\\\=0.21`

or

`=(21)/(100)`

So, the value of the given expression is equal to 0.21.
