Question

An u please help me out​

Answer 1

Rewrite the root be,

`√(39)=√(3\cdot13)=√(3)√(13)`

We know that
`√(3)\approx1.7,√(13)\approx3.6`

Write decimals as fractions and multiply them,

`(17)/(10)\cdot(36)/(10)=(612)/(100)=6.12`

So it should be on somewhere around the next tick from 6.

Hope this helps :)
