MULTIPLE SELECT QUESTION

Do you know the difference between Square Root and a Perfect Square?

(it's fine if you don't know)

No =.=!

Yes ↖(^ω^)↗

Kinda ⊙△⊙

Not really (??_??)?

Answer explanation

Square Root - A number times itself will produce a given number - 8 x 8 = 64

Perfect Square - A number whose square root is a whole number, not a decimal - Perfect Square = 16, 4 x 4

Not a Perfect square - 8, 2.82842712 x 2.82842712 = 7.99999997, rounded is 8
