4✓5 is the conjugate pair of one

Answer 2

Given,

$\[2\sqrt 3 - 4\sqrt 5 \]$

Solution,

Know that $\[\left( {a + \sqrt b } \right)\]$ is conjugate pair of $\[\left( {a - \sqrt b } \right)\]$

Calculate the conjugate pair.

$\[ = 2\sqrt 3 + 4\sqrt 5 \]$

Hence $\[ 2\sqrt 3 + 4\sqrt 5 \]$ is conjugate pair of $\[2\sqrt 3 - 4\sqrt 5 \]$.
