Question

How do you simplify `3x^sqrt2+x^sqrt2`?

Answer 1

`3x^sqrt2+x^sqrt2 = 4x^sqrt2`

Explanation:

There are 2 terms which are both like terms.

They can simply be added in the same way as `3x +x= 4x`

`3x^sqrt2+x^sqrt2 = 4x^sqrt2`

If `x^sqrt2` is treated as a common factor, the result is the same.

`x^sqrt2(3+1) = x^sqrt2 xx 4`

`4x^sqrt2`
