How many sig figs are in?

Question

0.0017100

i think 3? or is it 5?

Answer 1

May not know what sig figs are, but I'd say 5 since you don't need the zero to the left of the decimal, nor the 2 zeros after the 1, but 00171 affect the numbers value.

Nah, he's right.. check out

Answer 2

First, write this in scientific notation or standard form...

1.71 * 10^-3

1.71 has three significant figures. So 3 s.f.

I hope that helps. :)
