Answer:

Note:We can't find every numbers square using column method.

Answer 2

Answer:

Answer is 576.

Here, a=2 and b=4

Step 1: Make 3 columns and write the values of a²,2×a×b and b² in these columns.

 Column I Column II Column III  

a² 2×a×b  b²  

2² 2×2×4 4²

4 16   16 

Step 2: Underline the unit digit of b² (in Column III ) and add its tens digit, if any, with 2×a×b ( in column II )

 Column I Column II  Column III 

a² 2×a×b  b²  

4 16+1  16  

4 17 16

Step 3: Underline the unit digit in Column II and add the number formed by the tens and other digits if any, with a² in Column I.

Column I Column II Column III 

a²  2×a×b  b² 

4+1  17  16

5 17 16

 Step 4: Underline the number in column I.

 Column I Column II Column III 

a² 2×a×b  b²  

4+1 16+1  16  

5 17 16

 Step 5: Write the underline digits at the bottom of each column to obtain the square of the given number.

In this case, we have 576 as the square.
