I just started physics and have a few questions on significant digits.
I have to put this number into scientific notation
2 999 900
My answer is 2.3 * 10 (to the power of 6)
Is that right?
My other question is 8.83/0.002 = "4415"
To write it with sig digits I can only use one because of "0.002"
So would my answer be 4000?
And my last question is 8.56 * 2.3= "19.688"
With sig. digits = 20
Are these correct?
