Answer 2

Answer:

There are 2 solutions for this.

Solution 1

Multiplying the two digit integers and then adding the digits of its product gives us the answer.

Multiply 12*12=144

Sum of the digits of its product 1+4+4=9

Therefore 12*12=9

In the same way

Multiply 23*23=529

Sum of the digits of its product 5+2+9=16

And now

Multiply 34*34=1156

Sum of the digits of its product 1+1+5+6=13

Therefore 34*34=13

Solution 2

The square of the third number to the digit in the integer gives us the answer.

12*12 ,third number is 3, hence 3 power 2 is 9

23*23, third number is 4, hence 4 power 2 is 16

Similarly,

34*34, third number would be 5, hence 5 power 2 is 25

Therefore 34*34=25.
