To convert a number to standard form:write out the number starting with the first non-zero digit and continue until the last non-zero digit;put the decimal point after the first digit (if there is only 1 digit, the decimal point does not need to be written);count how many digits the decimal point needs to move to get back to where it was originally (if there was no decimal point as the number was a whole number it was "hiding" after the ones-digit, the last digit);if the decimal point needs to move left make this count negative;write ×10 to the power of this count after the number written in step 2.For 0.007 this gives 7 × 10⁻³

They are: 600, 30 and 3
3 100 423 080.
next number to this series is 554325. its look like this 15--add 1 to first digit and we get 2 and repeat two times and leave other digit.225 225-- its first digit is 2 and add 1 to it get 3 and write two time and write remaining digit as 3325. 3325-- its first digit is 3 and add 1 to it get 4 and write two time and write remaining digit as 44325. 44325-- its first digit is 4 and add 1 to it get 3 and write two time and write remaining digit as 554325.

Three hundred, Bro!
The answer is 3*3*2*1 = 18. If the leading digit is 0 it is not a 4-digit number.
To write 387 in standard notation, you simply write the number as it is: 387. Standard notation is the usual way we write numbers using digits, with each digit representing a different place value. In the number 387, the 3 is in the hundreds place, the 8 is in the tens place, and the 7 is in the ones place.
A smaller 3 digit number or a 2 digit number (99).
