If you are looking to answer the following questions: “what is the square root of 625?” The answer is 25.
ANSWER: square root of 625=25
The square root of a number (625 in this case) is a number (25 in this case) which multiplied by itself equals the number from which you are calculating the square root (625). Mathematically square root of 625 can expressed in the radical form or an exponent form as shown below:
- Radical form of the square root of 625: √625
- Exponent form of the square root of 625: (625)½ or (625)0.5
This symbol √ is called radical sign or radix. The number whose square root is being calculated is called the radicand. The radicand is the number underneath the radical sign (radix), in this case it is 625.

You will find all the information you need on the square root of 625 calculations below.
What is the square root of 625?
The square root of 625 is a number which multiplied by itself equals 625. Therefore, the square root of 625 is 25 and we write it √625=25 because 252=625. Since 252 is the same as 25 x 25 the following expressions is true:
625 = 252=25×25
Therefore
ANSWER: square root of 625=√625=25
Is 625 a Perfect Square?
A number is considered a perfect square if it is a product of squaring a whole number (called integer). 0, 1, 2, 3, 4, 7, 8, and 9 are all whole numbers (same as integers). Numbers such as -8, 7.025, or 5 ½ are not whole numbers. Remember squaring is when a number is multiplied by itself. For example, 81 is a perfect square because it is a product of 92 which is the same as 9×9. Notice 9 is a whole number (integer).
In our example the square root of 625 is 25. Since 25 is a whole number therefore 625 is a perfect square.
ANSWER: 625 is a whole number
Is the square root of 625 rational or irrational number?
A number is rational when it can be made by dividing a whole number by a whole number. A whole number which is also called an integer does not have a fractional part itself. Simply said a number is rational if it can be written as a fraction.
A quick method to determine if 625 is a perfect square. The square roots of perfect squares are all rational numbers. The square roots of numbers that are not a perfect square are all irrational numbers. Since we know that 625 is a perfect square therefore 625 is a rational number.
Principal square root of 625
Every positive number has two square roots. One of the square roots is positive and another one is negative. For example the square roots of 625 are -25 (negative) and +25 (positive) because (-25)^2=(+25)^2=625. The positive square root is denoted as “the principal square root”. Typically, when we are calculating “the square root of a number” we mean the principal square root. In our case it is positive 25 or +25 which is written as 25. As you may know if there is no minus (-) sign before a number it is a positive number.
Again the principal square root of 625 is 25.
Calculating the square root of 625 with a calculator
In order to calculate the square root of 625 with a basic or a scientific calculator you need to enter 625 and then press the key with this sign “√x”
√625 = 25
Calculating the square root of 625 in Excel and Google Sheets
There are two functions you can use to do this calculation. You can use the function SQRT () to calculate the square root of any number in Excel and Google Sheets. Click on a cell and type =SQRT(625). Hit enter. You will get 25.
You can also use the POWER function which works like an exponent is an equation. To find a square root of 625 type =POWER (625, 1/2). Remember square roots can be expressed as exponents as we discussed earlier in this article.
