Given that `sqrt(2)=1. 414 ,\ sqrt(3)=1. 732 ,\ sqrt(5)=2. 236\ a n d\ sqrt(7)=2. 646 ,` find the square roots of the following : `(276)/(50)`

Text Solution

Verified by Experts

`(276)/(50)`
`sqrt(276/50)`
`=sqrt((2times2times3times23)/(5times5times2))`
`=(2timessqrt3timessqrt23)/(5sqrt2)`
`=(2times1.732times4.796)/(5times1.414)`
`=16.613/7.07`
`=2.349`
