    @jdoe0001 is "Approximately, 63.02 *10^6 more kilograms is the mass of an aircraft carrier than the mass of a freight train" the answer?

    yes that's correct BUT scientific notation, uses only one number to the left of the dot you have two numbers \(\bf \underline{63}.02\times 10^6\)

    same thing, we simply move the dot over to the left one more slot so we end up with only one digit on the left side :)
