Write 95.43×10^-4 in scientific notation.

Question

Since we need to have the decimal place so that there is only one number on the left I guess I do this:

9.543

And to get back to where I was I need to go -1

So would this be the right answer:

9.543×10^1

I'm confused may you please help me

Answer 1

9.543x10^-3

When you move the decimal place to the right you add to the -4. i.e. (-4+1)
If it would have been to the left you would have subtracted from the -4. i.e. (-4-1)

Answer 2

Oh okay thank you!

Answer 3

the given explanation is reversed

when the coefficient is changed by moving the decimal point, the exponent is changed to keep the overall value the same

bigger coefficient means smaller exponent ... and vice versa
