Therefore

ANSWER: square root of 4389=√4389=66.249528300208

Is 4389 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 4389 is 66.249528300208. Since 66.249528300208 is not a whole number therefore 4389 is not a perfect square.

ANSWER: 4389 is not a whole number 

Is the square root of 4389 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 4389 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 4389 is not a perfect square therefore 4389 is not a rational number.

Principal square root of 4389

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 4389 are -66.249528300208 (negative) and +66.249528300208 (positive) because  (-66.249528300208)^2=(+66.249528300208)^2=4389. 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 66.249528300208 or +66.249528300208 which is written as 66.249528300208. As you may know if there is no minus (-) sign before a number it is a positive number. 

Again the principal square root of 4389 is 66.249528300208.
