Not sure what the question means, but the answer is either one of the following two:
(a) 18 * 18 = 182
(b) 18 * 18 = 324 = 3.24*102
72. 18*4=72
it equals thirty six
You may need to rephrase the question but if you mean this - 18 = 3d so what's d? Then the answer is 18 divide by 3 so 6
18 x 17 x 2 = 612
