20 divided by square root of 2




Here we will show you how to calculate 20 divided by the square root of 2. In fact, we will show you two different ways of calculating 20 divided by √2. We start by displaying the problem we are solving in mathematical terms, as follows:

20 ÷ √2  = 
   
20
 
   
2

Method 1
To solve the problem 20 divided by the square root of 2 using this method, we first find the square root of 2, and then we divide 20 by the answer to the square root of 2.

   
20
 
   
2
  ≈ 
   
20
 
   
1.4142136

   
20
 
   
1.4142136
  ≈  14.1421356


Method 2
With this alternate method, we first move the radical from the denominator to the numerator by multiplying the numerator and denominator by √2 like this.

   
20 × √2
 
   
2 × √2
  ≈ 
   
28.2842712
 
   
2

Then we divide the numerator by the denominator to once again get the answer to 20 divided by the square root of 2.

   
28.2842712
 
   
2
  ≈ 14.1421356
