What is the square root of 4?fffffffffffffffffffffffffffffffffffffffffffff

Answer 1

Answer:2

Step-by-step explanation:

2 squared is four

Squared is the opposite of square rooting.

And if you’re still confused, squaring is when you multiply a number by itself (ex. 4X4 aka 4 squared is 16)

Answer 2

Step-by-step explanation:

$\sqrt{a}=b\iff b^2=a\\\\\text{Therefore}\\\\\sqrt4=\pm2\ \text{because}\ (-2)^2=4\ \text{and}\ 2^2=4$
