this is easy .... its given ... 3.23 × 10 power 12
so if u c ... the decimal point in 323 if after the no. 3 .
and the power of 10 is 12
so we need to move the decimal point in 3.23 to the right 12 times
if we do that we will get 3230000000000.0 and then after going forward 12 times .... put a decimal point and add another 0 after it
and after putting commas in the right place following the international system , the answer will be : 3,230,000,000,000.0
