The general form of a number in scientific notation is a x 10n, where a must be between 1 and 10, and n must be an integer
thus 100 is 1x10^2 indicating 2 zeros or decimal moved 2 places now .001 is 1x10^-3 as it moved the opposite way. there are 2.2 cm in an inch so there are 22 mm per inch so you would us 75/22= and then put that in scientific notation
the answer is
3.40909090909090909
So you could say
3.409 draw a line over the 09 to
show it repeats forever and then write
x10^0 after it
so 3.409x10^0
standard notation puts one character
in front of the decimal point
what is the scientific n
otation of 75mm to inches?
