Question

Convert 0.00049 to scientific Notation

Answer 1

It is 4.9 x 10-4

Explanation:

So every time you do this type of scientific notation you need to count how many "0" there are and you need to check if they are in front of the number ( ex: 74.000 ) or if the are in the back ( ex: 0.0074 ) In this case since is in the back you would get the 10 and put it to the power of -4 since there is 4 zeros behind it. and then you just get the " 4 9 "( put a " . " between it ) and multiply it by
`10^(-4)`. ( You don't need to actually do the multiplication unless your teacher ask you to )

Hope this helps ✌️
