One way to write this is in scientific notation, which is a single digit, then a decimal and some number of decimal places, multiplied by 10 to some exponent. In scientific notation, this would be $1.7 × 10^{9}, because you would move the decimal place 9 spots leftwards to go from 1,700,000,000. to 1.7. 10000 would be written as 1. × 10^{5} in scientific notation, or could be written as just 10^{5}, which is a simpler exponential form.
