When you make the number smaller like this the exponent is positive. If you make the number larger then the exponent is negative such as .000067

You don’t need the zeros after the 5 because they don’t stand for anything unless you are doing significant digits. So answer would be a)

so if you had 5675400.0 you move the decimal place over to the left until there is only one number before the decimal so 5.675400 and then the amount of spaces that it got moved so in this case its 6 it would be 10^6 if the decimal place moved 7 spots it would be 10^7. you generaly dont write 5.675400×10^6 cause that defeats the purpuse of scientific notation

i hope i helped and if you nead help agein just ask you can email me at [email protected] or ask here

in b, even though it is correct, you may get confused later when doing your calculations

c is correct as well

When you place something in scientific notation, unless you are specifically required to carry out to a particular number of significant digits, it is acceptable to use solution (a) and truncate the zeros

always get i number to the left then count how many numbers till you get to the decimal and that is your exponent please choose me as best answer
