Answer 2

Hi ✋✋

Your questions:
$\sqrt{5} \: \: , \: \: \sqrt{6}$
We cannot get perfect square roots of these numbers because if we calculate the square root of these number then we get:$\\ \sqrt{5} = 2.2360679775......... \\ \sqrt{6} = 2.4494897427.........$

Here,
The dots meant that the calculation will be continued till infinity. Hence we can't find the perfect square root for such number although we can find square roots of numbers like,
$\\ \sqrt{4} = 2 \\ \sqrt{9} = 3 \\ \sqrt{25} = 5$
and so on.

Hence,
for convenience we simply write √5 , √6 so that we can find a accurate result for calculations.

Hope it helps!
