3a squared plus nine = 19a. 3a to the second power = 9a plus 9 = 19a.
(2+2)/(2+2)=1 (2/2)+(2/2)=2 (2*2)-(2/2)=3 (2+2+2)-2=4 (2+2)+(2/2)=5 (2*2*2)-2=6 ((2-.2)/.2)+2=7 2+2+2+2=8 (22/2)+2=9 ((2+2)*2)+2=10 ((2-.2)/.2)+2=11 (2+2+2)*2+=12 (22/2)+2=13 (2/.2)+(2+2)=14 2+(2/2)/.2=15 (2+2)*(2+2)=16 ...??????????=17 ((2+2)/.2)-2=18 ((2+2)-.2)/.2=19 22- √(2+2)=20
230.2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2 = 1073741824
2^18 = 262,144(2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2)
2 sqared is 4 so 2x2 sqared is 4
I don't know what sqared is but twelve squared is 122 or 12 x 12 = 144
