7869 = 88.707384134582=88.70738413458×88.70738413458

Therefore

ANSWER: square root of 7869=√7869=88.70738413458

Is 7869 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 7869 is 88.70738413458. Since 88.70738413458 is not a whole number therefore 7869 is not a perfect square.

ANSWER: 7869 is not a whole number 

Is the square root of 7869 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 7869 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 7869 is not a perfect square therefore 7869 is not a rational number.

Principal square root of 7869

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 7869 are -88.70738413458 (negative) and +88.70738413458 (positive) because  (-88.70738413458)^2=(+88.70738413458)^2=7869. 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 88.70738413458 or +88.70738413458 which is written as 88.70738413458. As you may know if there is no minus (-) sign before a number it is a positive number. 

Again the principal square root of 7869 is 88.70738413458.
