One nanometer is about 0.00000003937 of an inch. What is this number in scientific notation?
A. 3.937*10^-8
B. 3.937*10^8
C. 39.37*10^-7
D. 39.37*10^7
Is the answer A?
Thanks
have u guys ever thought some people cant afford tutors, have u ever thought that some dont have no one at all to help them, have u ever thought some people are trying their best and come here for help just to check answers, have u ever thought to not always criticize ppl for coming on here, There are alot of ppl that actually have trouble understanding things and just cant get it some of you make it hard or maybe even make them feel bad about themselves then they already have. just keep the bs comments and negativity to yourself. And why are you on here if your not so-called cheating, your worried about what someone else is doing. ITS NOT YOUR WORK Or if you want them to have a tutor PAY FOR IT. And sick of the teachers that always have something to say, when u dont even want help them. Just wanna whine and complain. Instead why dont you leave your info and ask if anybody needs help. leave these kids alone. And some of you are the reason why some kids dont even wanna go to school.

Period sis 😌.
ik im late. but, she told yall. -_-
Yup there you go my sista
scientific notation has a single digit number, followed by a decimal
only A andB fit that property.
look at the original number and compare it to A
the decimal moved 8 places to the right, count them
when you see 10^(negative) it represents a small number
when you see 10^(positive) it means you are dealing with a number greater than 10
now 0.0000.... looks pretty small to me, so
A is the correct choice, you were right.
