Question

round of each of the following quantities to two significant figures ​

Answer 1

Answer:

e.g. In 64,492 , 6 is the first significant figure. When we round off 64,492 to two sig. figs, that means in the answer we should have two non zero figures.The third figure(which is 4) is less than 5, so we drop them to zeros. The accuracy of the answer will depend on the number of significant figures.
