Write out the following number with an appropriate number of significant figuresWatch
please explain how to do this
Could you upload a picture of the actual question? The question that you've written seems strange.
y = 123456 +/- 89
So smallest possible value of y is 123545
And largest possible value of y is 123367
Therefore the appropriate number of digits is 3 (y = 123000).
<Rant> I have to say that I've always disliked the whole sig fig thing in these circumstances since you are throwing away almost an entire digit of accuracy just to be "correct". I'd rather the original form (including error range). </Rant>
