Homework Statement
This is a chem problem for adding sig figs with base ten. The problem is: 3.15x10^-4 + 6.99x10^1 + 5 all divided by 7.73x10^-4. I was trying to help my daughter with this.
Homework Equations
The Attempt at a Solution
I can do sig figs pretty well and these kinds of problems. The answer I got was 9.69x10^4. My daughter tells me this is wrong and the answer is: 9.04x10^1 + 8! I've never seen an answer for these kinds of problems written out like this - so what am I missing and how the heck did they come up with this?
thanks for the help.
