Between 7 and 8.

Explanation:

To determine this we must find the two perfect squares which surround 60. These are 49 and 64 which are the perfect squares of 7 and 8. Since 60 lies between 49 and 64 its square root will lie between 7 and 8.

$7 and 8$ $7" and " 8$

Explanation:

Consider $perfect squares$ $color(blue)"perfect squares"$ less than 60 and just greater than 60.

These are $49 and 64$ $color(red)(49)" and " color(red)(64)$

$\Rightarrow \sqrt{49} < \sqrt{60} < \sqrt{64}$ $rArrsqrtcolor(red)(49) < sqrt60 < sqrtcolor(red)(64)$

$\Rightarrow 7 < \sqrt{60} < 8$ $rArr7 < sqrt60 <8$
