Question

6. Evaluate: (√5 + 2 √2) square - (start √5 - √8) square​

Answer 1

Answer:

HOPE IT HELPS !!

Step-by-step explanation:

[(√5)²+(√2)²-2×√5×√2]+[(√8)²+(√5)²-2×√8×√5]

[5+2-2×√10]+[8+5-2×√40]

7-2√10+(13-4√10)

-2√10(7+11)

-2×18√10

-32√10

Answer 2

Answer:

$= > {( \sqrt{5} + 2 \sqrt{2} )}^{2} - {( \sqrt{5} - \sqrt{8} )}^{2} \\ = > {( \sqrt{5}) }^{2} + 2 \times \sqrt{5} \times 2 \sqrt{2} + {(2 \sqrt{2}) }^{2} \\ - ( {( \sqrt{5}) }^{2} - 2 \times \sqrt{5 } \times 2\sqrt{2} + {( \sqrt{8} )}^{2} \\ = > 5 + 4 \sqrt{10} + 8 - 5 + 4 \sqrt{10} - 8 \\ = > 8 \sqrt{10} \\ \red{\mathfrak{\underline{\large{Hope \: It \: Helps \: You }}}} \\ \blue{\mathfrak{\underline{\large{Mark \: Me \: Brainliest}}}}$
