Question

Which is the correct product of the significant figures 3.278 and 4.23

Answer 1

count the number of significant figures in 3.278, and the number of significant figures in 4.23. whichever count is lower, that's how many sig figs should be in your solution

from there, multiply 3.278 and 4.23, then round to the appropriate number of sig figs you determined from the previous step
