Find the value of `sqrt(15625)` and the use it to find the value of `sqrt(156. 25)+\ sqrt(1. 5625.)`

Explanation

`Given : sqrt(15625)`

`sqrt(15625)=sqrt (5 xx 5 xx 5 xx 5 xx 5 xx 5)`

`sqrt(15625) = 125`

`therefore sqrt(156.25)+ sqrt(1. 5625.)`

`=>sqrt(15625/100)+ sqrt(15625/10000)`

`=>125/sqrt(10 xx 10)+125/sqrt(100 xx 100)`

`=>125/10+125/100`

`=>12.5+1.25`
