 Square Root of 136: √136 = 11.661
 Square of 136: 136^{2} = 18,496
What Is the Square Root of 136?
 The square root of 136 is 136 raised to the power ½. 136^{½ }= (number × number) ^{½} = √136
 11.661 × 11.661 = √136 and 11.661 × 11.661 = √136
 √136 = ± 11.661
Is Square Root of 136 Rational or Irrational?
The square root of 136 is an irrational number where the numbers after the decimal point go up to infinity. √136 = 11.6619037897 which cannot be expressed as a rational number of the form p/q. Thus square root of 136 is an irrational number.
How to Find the Square Root of 136?
The square root of 136 or any number can be calculated in many ways. To mention a few: Prime factorization method, approximation method and the long division method.
Square Root of 136 in its simplest radical form
 Prime factorization is expressing the number as a product of its prime factors. 136 = 2 × 2 × 2 × 17
 √136 = √(2 × 2 × 2 × 17)
 √136 = √(2 × 2 × 2 × 17) = 2 √34
 Thus square root of 136 in its simplest radical form = 2 √34
Square Root of 136 by the Long Division Method
The long division method helps us to find the more accurate value of square root of any number. Let's see how to find the square root of 136 by the long division method. Here are the desirable steps to be followed.
 Write 136 as 1 36 00 00 00. Divide 1 by 1 and get the remaider as usual. Bring the pair of 36 down.
 Multiply the quotient by 2 and have 2x as the new divisor.
 Find a number in the place of x such that 2x × x gives 36 or less than that. We find 21 × 1 is 21. Subtract it from 36 and get the remainder as 15.
 Multiply the quotient by 2 and have 22x as the new divisor. Bring the pair of 00 down.
 Find a number in the place of x such that 22x × x gives 15 00 or less than that. We find 226 × 6 is 1356. Subtract it from 1500 and get the remainder as 144.
 Multiply the quotient by 2 and have 232x as the new divisor. Bring the pair of 00 down.
 Find a number in the place of x such that 232x × x gives 1 44 00 or less than that. We find 2326 × 6 is 13956. Subtract it from 1 44 00 and get the remainder as 4 44.
 Repeat the process until we approximate to 3 decimal places.
 Thus √136 = 11.661 to the nearest thousandths.

 √136 is an irrational number.
Square Root of 136 Solved Examples

Example 1: Sia is creating a right triangle on her embroidery work. She makes the "L" shape with the thread running 10 inches down and 6 inches right. What will be the length of the third side to the nearest tenth?
Solution:
The desired third side we are looking for is the hypotenuse.
10^{2 }+ 6^{2 }= hypotenuse^{2}
hypotenuse^{2} = 100 + 36 = 136
hypotenuse = √136 = 11.661
Rounding it off to the nearest tenth, we get 11.6 inches. 
Example 2: Stacey has a box that has the surface area of 1.36 square inches. What will be the area of the crepe paper she needs to buy to decor the top of the box?
Solution:
Area = side × side
1.36 = side^{2}
side = √1. 36 = √136/√100 = √136/10 = 11.661/10 = 1.661 inches
She needs to buy atleast a crepe that is 2 inches long.
Therefore, the area of the crepe paper she needs to buy = side × side = 4 sq. inches
