A square root is a number raised to the exponent (power) 1/2.
They are not.
Exponents are usually written like this: 3^2 means "3 to the second power". Square roots are often written with sqrt in front, such as as sqrt(5)
The square roots of 21 are 4.5826 (rounded) and the negative of the same number.

Sure. the square root of 6 times 4 square roots of 6 is the same as the square root of 6 to the power of five which can be reduced to 6 squared times the square root of 6. The resulting answer is 36 root 6.
I posted an answer about cube roots of complex numbers. The same info can be applied to square roots. (see related links)
Every number has two square roots. They're the same size, but one is positive and the other is negative.

1 and the positive and negative square roots of 2
There are two square roots of i: (-1/square root 2)(1+i) and (1/square root 2)(1+i) so these are i to the one half power. Now to find -i to the one half power, multiply either of these by i, since i2 is -1. So (-i/square root 2)(1+i) and (i/square root 2)(1+i) are the square roots of -i. Verify this by direct multiplication.
Every positive number has two square roots. Their absolute values are the same. One is positive and the other is negative.
