first method 108 ^ 2 108+8// 8^2 =116 64 second method 108   08 108    08

=
116   64 =11664

Third method 108 ^ 2 D(1)//D(10)//D108//D08//D(8) =1 //0 // 16 // 0//64 = 11664

forth meyhod 108 ^2 10 // 8 a=10 b=8 (a+b) ^2 =a^2 + 2*a*b + b ^2 =100 + 2*10*8 + 64 =100//160//64 =100+16//0+6//4 =116 64

fifith method 108 ^2 A=10, B=8 (B/A)=(8/10) =4/5

A^2   (A^2)(B/A)    (A^2)*(B/A)*(B/A) 100    100*(4/5)    100*(4/5)*(4/5) 100     80            64       +80

=
======================= 100   160           64 =11664 sixth method A^2-B^2 =(A+B)(A-B) A^2=(A+B)(A-B)+B^2 A=108, B=8 108^2= (108+8)(108-8)+64    =116x100 +64 =116 64 seventh method 1 0 8 x 1 0 8

=
=========== 1x1//0x0//[(1x8)+(0x0)+(1x8)//0//8x8 =1//0//16//0//64 =116 64
