The number 80710 is rounded to 2 SF?
The choices are confusing
A) 80700 B)81000 C)8070 D)8100 E) None
Is E correct?
B and D are both 2SF A and C are 3SF???
Thanks for you help.
You started out with over 80 thousand, so C and D are not correct. The two significant figures should be in the ten thousand and thousand columns.
