Question

Between what two consecutive integers does `sqrt21` lie?

Answer 1

`sqrt21` lies between `4 and 5`

Explanation:

We know that,

`color(red)(sqrt16 )< sqrt21 < color(red)( sqrt25)`

`=>color(red)(4 ) < sqrt21 < color(red)( 5)`

Hence `sqrt21` lies between `4 and 5`

Answer 2

`5^2=25 and 4^2=16" so "sqrt21" is between "4 and 5`
