$$5\sqrt{13}+\sqrt{6}-7\sqrt{13}$$

i am not sure what you are asking,
You can simplify the expression by combining the sqrt(13)
so the equation becomes
$$\sqrt{6}-2\sqrt{13}$$
from there, can you use a calculator?

I don't know what it is asking either and I don't have a book I even googled it and couldn't find anything

anonymous · Answer

i believe the simplified answer i gave before is the one you are looking for. A calculator gives you an approximate solution not an exact answer

anonymous · Answer

for example the exact solution of $$\sqrt{8}=2\sqrt{2}$$

anonymous · Answer

this is just a fancy way of asking simplify the expression as much as you can
