this is your answer Thankyou

Answer 2

Answer:

Yes. It is rational.

Step-by-step explanation:

We can rationalise it, as follows :

$\frac{4}{3 \sqrt{5} } = \frac{4}{3 \sqrt{5} } \times \frac{ \sqrt{5} }{ \sqrt{5} }$

$= \frac{4 \sqrt{5} }{3 \times 5} = \frac{4 \sqrt{5} }{15}$

So, finally it's rational as it can be expressed in p/q form and q is also not equal to 0.
