MathMate,
For $58,200,000,000., move the decimal point to the left until it is to the right of the first nonzero digit (5). Multiply by 10 raised to the power of the number of digits moved (10). So the answer is
5.82*10^{10}
I will leave you to do the second one. Post your answer for checking if you wish.
