How do you subtract radicals?


Example wise.
Answered by I see you have graph paper. You must be plotting something.
Lets say you have sqrt16-sqrt8. sqrt8=2sqrt2 and sqrt16=4sqrt2 so the answer is 2sqr2, or sqrt8. Or, you could have sqrt27-sqrt3. sqrt27=3sqrt3, so it is 3sqrt3-sqrt3=2sqrt3=sqrt12.
