Square Root of 5: 2.23606797749979

Square Root of 5 in exponential form: (5)½ or (5)0.5

Square Root of 5 in radical form: √5

What Is the Square Root of 5?

Let us first understand the meaning of square root. The square root of a number is the number which, when multiplied to itself, gives the product as the original number. Consider the example:

52 = 5 × 5 is 25

Here 5 is called the square root of 25. 25 is a perfect square. So the square root of 25 is 5. Now, what is the square root of 5? Does that mean non-square numbers cannot have a square root? Non-square numbers also have a square root, just that they are not whole numbers. For real numbers a and b,

a2=b is a=√b

The square root of 5 in the radical form is expressed as √5 and in exponent form, it is expressed as 5½. The square root of 25 is the inverse operation of squaring 5 and -5

5 × 5=25

(-5) × (-5) = 25. 

Let us look at the square root of 5
