6.04800 x 10^5
explanation: just imagine there is a decimal point at the end of that number so that it looks like this : 604,800. then what you have to do is just move the decimal point so that it is between the 6 and the 0. and since you move the decimal point to the left 5 times, your answer is 6.04800 x 10^5. when you move the decimal to the left the exponent is positive, when you move the decimal to the right the exponent is negative
