The simplest of all, of course, is to use a calculator. All scientific and many basic calculators have the square root function built in.
If the number is a perfect square then you can find the square root by "reverse engineering". If 6*6 = 36 then the square root of 36 is 6 (or -6). This will only work for perfect squares (or ratios of perfect squares, such as 4/9), and not for other numbers.
Alternatives to the above two are more complicated. There is a method which is a bit like long division but you have to adjust the divisor at each step. It is, unfortunately, too complicated (for me) to explain here.
You can use numerical methods (eg Newton-Raphson) to make an estimate and then improve on it.
You can also use logarithms if you can lay your hands on logarithm tables. If you want to find the square root of x, find log(x), divide that number by 2 and then look up the antilog of the answer. Easy if you have log tables; impossible if you don't.

What is the simplied eqation square root of 30 multiplied by the square root of 12?
Multiply the thirty and the twelve together to get three hundred and sixty. Now you have the square root of three hundred and sixty. Then take out any square roots you know. In 360, the obvious choice is 36. Take the square root of 36, six, out of the square root. When you take thirty-six out, you are left with the square root of ten. You now have six square root of ten.
How do you find the length of the side of the square?
Measure it. Or take a quarter of its perimeter. Or take the square root of its area. Or take the cube root of a cube built on the square
Is root 2 a rational number?
The square root of 2 is irrational. In general, the square root of a positive integer is either an integer (if you take the square root of a perfect square), or it is irrational.
Is the square root of .75 rational?
No. The square root of most numbers is irrational - only if the number of which you take the root happen to be perfect squares, do you get a rational root. In this case, to take the square root of 3/4, 3 is not a perfect square, so the root is not rational. Or you can take .75 to be 75/100; once again, 75 is not a perfect square, so the root is irrational.
How can you find the length of a side on a square if you know the square root?
The square root of what? If you take the square root of the area, the answer will be the length of the side. If the area is, for example, in square meters, the length of a side will be in meters.
How do you figure the square root of a house?
You don't take the square root of a house, or of any object for that matter. You can take a square root of numbers, and of certain measurements, for example, the house's surface area.You don't take the square root of a house, or of any object for that matter.

What happens when you take the square root of a non-perfect square?
You get an irrational number as the square root.

What is the principal square root by simplifying the radical 24?
The idea is to take any perfect square out of the square root sign. root(24) = root(4 x 6) = root(4) x root(6) = 2 x root(6).The idea is to take any perfect square out of the square root sign. root(24) = root(4 x 6) = root(4) x root(6) = 2 x root(6).The idea is to take any perfect square out of the square root sign. root(24) = root(4 x 6) = root(4) x root(6) = 2 x root(6).The idea is to take any perfect square out of the square root sign. root(24) = root(4 x 6) = root(4) x root(6) = 2 x root(6).

What is the square root of space?
That makes no sense. You take the square root of numbers, and of certain measurements - not of "space".

Are square root irrational?
Usually they are. More specifically, if you take the square root of a positive integer, there are only two possibilities:* If you take the square root of a perfect square, you get a whole number. * In all other cases, you get an irrational number.
