# How do you combine sqrt 3 + 2?

Apr 27, 2018

You cannot combine values that have different indices

So we have ${3}^{\frac{1}{2}} + {2}^{1}$

Since these are different indices, we can't combine them

Hope this helps!

You can't

#### Explanation:

You cannot combine them.

only roots with the same root can be combined.

Eg:

$\sqrt{4} + 4 \sqrt{4} = 5 \sqrt{4}$

whereas...

$\sqrt{4} + \sqrt{5} = \sqrt{4} + \sqrt{5}$

You could simplify the root if possible then combine the terms, for example:

$\sqrt{4} + 2 = 2 + 2 = 4$

but $\sqrt{3}$ cannot be simplified, so we cannot do this.
