Question

How do I find the exact value of this expression? (5)sqrt13+sqrt6 -7*sqrt13

The equation will also be in the comments

Answer 1

\[5\sqrt{13}+\sqrt{6}-7\sqrt{13}\]

Answer 2

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?

Answer 3

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

Answer 4

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

Answer 5

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

Answer 6

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

Answer 7

Thanks
