($\sqrt{5}$ - $\sqrt{2}$ ($\sqrt{5}$ + $\sqrt{2}$

Answer 1

Answer:

$( \sqrt{5} - \sqrt{2})( \sqrt{5} + \sqrt{2} )$

${( \sqrt{5}) }^{2} - {( \sqrt{2}) }^{2}$

$5 - 2$

$3$

Ans. 3

Hope it helps.

Answer 2

Answer:

Step-by-step explanation:

$\Large{\mathtt{( \sqrt{5} - \sqrt{2} )( \sqrt{5} + \sqrt{2} ) }}$

$\Large{\mathtt{ { (\sqrt{5}) }^{2} - ( { \sqrt{2} )}^{2} }}$

$\Large{\mathtt{5-2}}$

$\Large{\boxed{\mathtt{\rightarrow3}}}$
