3 has no square root but 12 has.
how? any number multiplied to itself doesnt have the answer 12

we'll have to simpilfy it by finding factors
(consider the brace as the radical sign)

{12
{4×2 (4 has a square root[2×2])
2{2 (you have to write the simplified number or variable outside of the radical sign

I hope this was helpful
