Question

How do I change this number to standard scientific notation 5.408?

Answer 1

@anitasonia98

Answer 2

well, it is already almost there. You just need to write

\(5.408\times 10^0\)

Answer 3

really?

Answer 4

yes, scientific notation is in the form \(a.bcde..\times 10^k\)

Answer 5

in other words we only want one number before the decimal

Answer 6

How do I write 72.41 x 10^-2 in standard scientific notaiton?

Answer 7

if it were \(10.58\) then we would write \(1.058\times 10^{-1}\)

Answer 8

Ooh Thanks

Answer 9

we want one number in front of the decimal

If you need to move the decimal to the left to make that happen, then you subtract one from the power of 10

if you need to move the decimal to the right then you add one to the power of 10

Answer 10

is it weird they must the word standard in front of scientific notation? seems like an extra word to me.

Answer 11

I think standard means base 10?

Answer 12

so there is unstandard scientific notation? :p

Answer 13

\(72.41\times 10^{-2}=7.241\times 10^{-3}\)

Answer 14

I have no idea, but if there was a standard, surely it would be the one we know :)

Answer 15

Maybe some Pigmy tribe uses something different.

Answer 16

ps I have that backwards, if we move left add 1, if we move right subtract 1.
