You can put this solution on YOUR website! I think you mean >>
You can not do many things in this problem the only thing is just a multiplication of the square's such that 7*3 and the equation will look like >>
The remaining part is just calculation by a calculator.
Let me give you another example such that :
First you will force to make the numbers under the square same,if they are multiplication of same number. In this question 2 and 8 are come from 2. So that,you will make the numbers under the square 2. Observe this >>
You wrote 8 as 2^3 after then you'll multiply the upper square parts as 7*3 and 9*3 and you'll get >>
After then (it's a rule) you'll sum 21 and 27 and write as
