Find

Square of 26 using column method

Solution

We need to find square of 26 using column method

Number is 26

Here a = 2 and b = 6

Step 1) Make a table with 3 columns and write the values of a², 2ab and b² in these three columns

Step 2) Underline the unit digit of b² and add the tens digit to 2ab term if any

Step 3) Underline the unit digit formed in 2ab column and add its tens digit to a² term column if any

Step 4) Underline the digit at a² term column

Step 5) Write all the underline digits and thats our square

26² = 676

Therefore the square of 26 using column method is 676.
