What is the square root of 142?

The square root of 142 is a number which multiplied by itself equals 142. Therefore, the square root of 142 is 11.916375287813 and we write it √142=11.916375287813 because 11.9163752878132=142. Since 11.9163752878132 is the same as 11.916375287813 x 11.916375287813 the following expressions is true:

142 = 11.9163752878132=11.916375287813×11.916375287813

Therefore

ANSWER: square root of 142=√142=11.916375287813

Is 142 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 142 is 11.916375287813. Since 11.916375287813 is not a whole number therefore 142 is not a perfect square.

ANSWER: 142 is not a whole number 

Is the square root of 142 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 142 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 142 is not a perfect square therefore 142 is not a rational number.

Principal square root of 142

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 142 are -11.916375287813 (negative) and +11.916375287813 (positive) because  (-11.916375287813)^2=(+11.916375287813)^2=142. 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 11.916375287813 or +11.916375287813 which is written as 11.916375287813. As you may know if there is no minus (-) sign before a number it is a positive number. 

Again the principal square root of 142 is 11.916375287813.

Calculating the square root of 142 with a calculator

In order to calculate the square root of 142 with a basic or a scientific calculator you need to enter 142 and then press the key with this sign  “√x”

√142 = 11.916375287813
