If you are familiar with some basic squares, you may know that (x+2)2 = x2 + 4x + 4. The coefficients here are 1,4,4 - not quite in the same order but pointing in the right direction. From the above you may deduce that (2y+1)2 = 4y2 + 4y + 1 Better, but not quite there. But you should also know that 22 = 4 so that 2002 =40000. And then it should all fall into place: 40401 = (+/- 201)2 The simpler alternative is to use the square root function on your calculator!
There are infinitely many of them. They include square root of (4.41) square root of (4.42) square root of (4.43) square root of (4.44) square root of (4.45) square root of (5.3) square root of (5.762) square root of (6) square root of (6.1) square root of (6.2)
A principal square root is any square root that's answer is positive, and a perfect square root is a square root that's answer is an integer.
square root of 20 = square root of 4 * square root of 5. square root of 4 = 2, so your answer is 2 square root of 5.

It's not a square if it has no root. If a number is a square then, by definition, it MUST have a square root. If it did not it would not be a square.
square root 2 times square root 3 times square root 8
The principal square root is the non-negative square root.
We use the property of square roots that says the square root of (ab)=square root (a) multiplied by square root of b So square root (4x)=square root (4) mutiplies by square root of x =2(square root (x)) 2sqrt(x)
A principal square root is any square root that's answer is positive, and a perfect square root is a square root that's answer is an integer.
