I'm pretty sure you mean scientific notation so I'll explain that.
37,200,000,000,000.0 You have to start by moving the decimal over until the number at the front of the equation is between one and 9.99. You move it over 13 times, which is the number that the base, 10, will be to the power of. Your first number is 3.72, so you plug that in your equation and:
3.72X10^{13}
there's your number in scientific notation
