Examine whether the following numbers are rational or irrational:$ \sqrt{3}+\sqrt{5} $
Given:
\( \sqrt{3}+\sqrt{5} \)
To do:
We have to classify the given number as rational or irrational.
Solution:
A rational number can be expressed in either terminating decimal or non-terminating recurring decimals and an irrational number is expressed in non-terminating non-recurring decimals.
Therefore,
$\sqrt{3}=1.7320508..........$
$\sqrt{5}=2.23606............$
The decimal expansion of \( \sqrt{3} \) and \( \sqrt{5} \) is non-terminating and non-recurring.
The sum of two irrational numbers is an irrational number.
Therefore, \( \sqrt{3}+\sqrt{5} \) is an irrational number.
