Question

The simplest rationalising factor of root 5 minus root 3 is

Answer 1

root5 plus root 3 is the simplest rationalising factor of root5 minus root3

Answer 2

The simplest rationalizing factor of $\sqrt{5}-\sqrt{3}$ is $\sqrt{5}+\sqrt{3}$.

Step-by-step explanation:

The given expression is

$\sqrt{5}-\sqrt{3}$

The simplest rationalizing factor of $\sqrt{a}-\sqrt{b}$ is $\sqrt{a}+\sqrt{b}$.

We need to find the simplest rationalizing factor of $\sqrt{5}-\sqrt{3}$.

Here, a =5 and b=3, so the simplest rationalizing factor is

$\sqrt{a}+\sqrt{b}=\sqrt{5}+\sqrt{3}$

Therefore, the simplest rationalizing factor of $\sqrt{5}-\sqrt{3}$ is $\sqrt{5}+\sqrt{3}$.
