20 divided by square root of 4




Here we will show you how to calculate 20 divided by the square root of 4. In fact, we will show you two different ways of calculating 20 divided by √4. We start by displaying the problem we are solving in mathematical terms, as follows:

20 ÷ √4  = 
   
20
 
   
4

Method 1
To solve the problem 20 divided by the square root of 4 using this method, we first find the square root of 4, and then we divide 20 by the answer to the square root of 4.

   
20
 
   
4
  = 
   
20
 
   
2

   
20
 
   
2
  =  10


Method 2
With this alternate method, we first move the radical from the denominator to the numerator by multiplying the numerator and denominator by √4 like this.

   
20 × √4
 
   
4 × √4
  = 
   
40
 
   
4

Then we divide the numerator by the denominator to once again get the answer to 20 divided by the square root of 4.

   
40
 
   
4
  = 10
