Question

How do you add radicals? Medals

Answer 1

lmfao just did that stuff

Answer 2

\[\sqrt{10}+\sqrt{8}\]

Answer 3

I think it's \[\sqrt{18}\] am I right?

Answer 4

no you cannot add them

Answer 5

you can write \(\sqrt8=2\sqrt2\) if you like, but you cannot add them like that

Answer 6

just like \(\sqrt{50}+\sqrt{50}\neq \sqrt{100}=10\)

Answer 7

umm so I can't add them? why not

Answer 8

Can I simplify it?

Answer 9

There's no way to simplify this down nicely, this is the best I can get:

\[\sqrt{10}+\sqrt{8}=\sqrt{5*2}+\sqrt{4*2}=\sqrt{5}\sqrt{2}+\sqrt{4}\sqrt{2}=(\sqrt{5}+\sqrt{4})\sqrt{2}=(2+\sqrt{5})\sqrt{2}\]

Answer 10

@TaylorS11 because Maths doesn't work like that.

\[\sqrt{9}+\sqrt{16} = 3 +4 = 7, \sqrt{9+16}=\sqrt{25}=5\]

They aren't equal.

Answer 11

Ugh math -_- whyy okay thanks
