  • 1 x (11 x 11) = 121 = 1 + 2 + 1 = 4
  • 4 x (11 x 11) = 4 x 121 =4 x(1 + 2 + 1) = 16
  • 9 x (11 x 11) = 9 x 121 =9 x(1 + 2 + 1) = 36

I simply rewrote the equation in terms of variables. (2n/11)^2 = P; where P is the product of the expression on the left side of the equation and N has a factor of 11. When substituting "33" in for "n", the left side of the equation will equal 36 since 2 times 33 is 66 and 66 divided by 11 is 6 and finally 6 squared is 36.

11 x 11 = 2 x 2 =4 because {1+1}*{1+1} = 4 22 x 22 = 4 x 4 =16 because " " " = 16
33 x 33 = 6 x 6 = 36 because " " " = 36

11 x 11=>(1+1) x (1+1)=2 x 2=4

22 x 22=>(2+2) x (2+2)=4 x 4=16

33 x 33=>(3+3) x (3+3)=6 x 5=36
