Find the sum of $x \sqrt{5}$ and $4x \sqrt{5}$ .

STEP 1

Assumptions1. We are given two terms $x \sqrt{5}$ and $4x \sqrt{5}$ . . Both terms are similar as they have the same variable $x$ and the same radical $\sqrt{5}$ .
3. We can add similar terms by adding their coefficients.

STEP 2

We can write the given expression as a sum of two similar terms.
$x \sqrt{5} +4x \sqrt{5}$

STEP 3

We can add similar terms by adding their coefficients. The coefficient of $x \sqrt{5}$ is1 and the coefficient of $x \sqrt{5}$ is.
$(1 +) x \sqrt{5}$

STEP 4

Calculate the sum of the coefficients.
$x \sqrt{}$ So, the sum of $x \sqrt{} +4x \sqrt{}$ is $x \sqrt{}$ .
