There is always 1 digit in front of the comma in scientific notation, so we count how many times we must move the comma front he end of the number to get it to 1 digit in front.

#4.8 xx 10^5#


scientific notation is a means of expressing very large or very small numbers in a shorthand form

the standard form is a x #10^n#where a must be a number between 1 and 10 and n is an integer,

first write 480000 as a number between 1 and 10 ie. 4.8

now we have to multiply by # 10^5# to retain the value of the original.

so 480000 = 4.8 x # 10^5#
