can someone ans this question ​

Answer 1

(7√7 - 4√3) + (4√7 - 2√3)

= 7√7 - 4√3 + 4√7 - 2√3

= 11√7 - 6√3

Answer 2

${\sf{{\pink{Given:}}}}$

$↦\sf\:(7\sqrt{7} - 4\sqrt{3}) +(4\sqrt{7} - 2\sqrt{3})$

Opening the brackets :

$↦\sf\:7\sqrt{7} - 4\sqrt{3} +4\sqrt{7} - 2\sqrt{3}$

Pairing the like terms :

$\sf↦\:7\sqrt{7} +4\sqrt{7} - 4\sqrt{3} - 2\sqrt{3}$

Now adding :

$\sf↦\:11\sqrt{7} - 6\sqrt{3}$

So final answer :

$\small{\underline{\boxed{\mathrm\red{➪\:11\sqrt{7} - 6\sqrt{3} }}}}$
