What is a Square Root?
A square root is the number that when multiplied by itself produces a given number. For instance, the square root of 25 is 5 because when 5 is multiplied by 5, the result is 25. The mathematical symbol for square root is a radical sign, which looks like this: √. The square root of a given number can be either positive or negative.
The square root of a number can be found by trial and error, although this isn't the most efficient method. An easier way to find the square root of a number is to use a calculator. Simply enter the number and press the "√" button to find the answer.
How to Solve Square Roots
One way to solve square roots is to use the long division method. To do this, divide the number by the largest number possible. Then, divide the result by the largest number possible. Continue this process until the answer is a whole number. This is the square root of the number.
Factoring Method
Another way to solve square roots is to use the factoring method. To do this, factor the number into two smaller numbers. The smaller numbers must have a sum that is equal to the number being factored. Then, the square root of the number will be the sum of the square roots of the two smaller numbers.
Simplifying Square Roots
In some cases, the square root of a number may be a non-terminating decimal or a fraction. To simplify the square root, first convert it into a fraction. Then, use the factoring method to find the square root. Finally, simplify the fraction to get the answer.
Why Square Roots Are Useful
Square roots are useful for solving many mathematical problems. For instance, square roots can be used to solve equations involving squared numbers. Squared numbers are numbers that have been multiplied by themselves. Square roots can also be used to find the area of a square or the volume of a cube.
