Question

3 sqrt 2+7 sqrt 2

Answer 1

They have the same base, which is the sqrt2.
So you can add the 3 and the 7.
Leaving you with 10sqrt2.
Make sense?

Answer 2

\[\sqrt[3]{2}+\sqrt[7]{2}\]

Answer 3

is it that or \[3\sqrt{2}+7\sqrt{2}\]
lol big difference

Answer 4

not really
so you mean you add 3 and 7 and

Answer 5

Think of the square root 2 as x. So 3x + 7x = 10x.

Answer 6

ok i got it thanks what if the squares were different

Answer 7

hmm give me an example?

Answer 8

\[\sqrt[6]{3}+\sqrt[15]{2}\]

Answer 9

you shouldn't type it like that because it means something completely different to
6 square root 3 + 15 square root 2.
But you can't add them together because the bases are different.
So for example is square root 3 = y and square root 2 = x
You can't add 6y + 15x.
Do you get it?

Answer 10

yes

Answer 11

Excellent!.
