Question

5(radical din 5 +2 radical 7)+2(raical7+3radical5)​

Answer 1

Hei !

5(radical din 5 +2 radical 7)+2(radical7+3radical5)​

5(√5 + 2 √ 7) + 2 ( √7  + 3√5 )

5√5 + 10√7 + 2√7 + 6√5

11√5 + 12√7

Answer 2

$5( \sqrt{5} + 2 \sqrt{7} ) + 2( \sqrt{7} + 3 \sqrt{5} )$

$5 \sqrt{5} + 10 \sqrt{7} + 2 \sqrt{7} + 6 \sqrt{5}$

$11 \sqrt{5} + 12 \sqrt{7}$
