could you possibly help? :)

A=41.918 g
B=24.83 g
C=24.83 g
D=41.918 g
A+B+C+D= ? g   
Round answer to 4 significant figures and use scientific notation, such as
$1.300\times 10^2 g$

is that the complete answer? @mathmate

mathmate · Answer

Yes, if you did the calculation for A+B+C+D.
The number in scientific notation is to give you an idea what the answer $should$ look like, as per the question.  The value of the number is not the answer.
