Hi, can anyone explain to me why 900 (or any similar numbers) can be given as one, two or three significant figures? I don't get it.

900 may be written in scientific notation as

$\displaystyle 90X10^1$

$\displaystyle 9X10^2$ - Feb 7th 2011, 03:14 PMtopsquark
Also 900 to three sig figs is 900. <--A decimal point, not a period.

PS Also, to 1 fig we have 9 x 10^2

For 2 fig we have 9.0 x 10^2

For 3 fig we have 9.00 x 10^2

Also the 90 x 10^1 has only has 1 sig fig
