Question

how many non square number between 9 and 16​

Answer 1

$We \:know \: that ,$

$\pink { The \: number \:of \:non\: square }$

$\pink{ between \:n^{2} \:and \: (n+1)^{2} }$

$\blue{ = 2n }$

$Here , n^{2} = 9 = 3^{2}$

$and \: (n+1)^{2} = 16 = (3+1)^{2} = 4^{2}$

$\pink { n = 3 }$

$\therefore \blue{number \:of \:non\: square }$

$\blue{ between \:3^{2} \:and \: 4^{2} }$

$= 2 \times 3$

$\green { = 6}$
