The possible roots of √9 are +3 and -3.
What is root of a number?
In mathematics, a number's root is the number that, when multiplied by itself, yields the original number. For instance, since 7 x 7=49, the square root of 49 is 7. In this instance, 7 is referred to as the square root of 49 since it must be multiplied twice to produce the number. 3 because
3 x 3 x 3 = 27 is the cube root of 27.
We have to find the possible roots of √9.
The number 9 is not a prime number and is an odd number.
The multiple of nine can be expressed as follows:
1 x 9 = 9
3 × 3 = 9
9 × 1 = 9
You are aware that the number 9 is a multiple of three or that the result of multiplying three times itself is nine. Consequently, the square root of 9 can be expressed as;
[tex]\sqrt{9} = \sqrt{3*3} = \sqrt{3^2}[/tex]
The square root of a number is cancelled by the square. As a result, when we square the above expression's square root, we obtain.
√9 = ±3
In essence, taking a number's square root yields two root values, one with a +ve symbol and the other with a -ve symbol.
Therefore, we can say that the roots of 9 are +3 and -3, or that the value of the square root of 9 can be expressed as +3 and -3.
