tolong ya dibantu,,

Answer 1

1. 2√5 ( √5 + √2 )
= 2x5 +√10
=10+√10
2. √6 ( √8 - 2 √2 )
=√48 -2√12
=4√3-4√3
=0
3. √6 ( 3 √3 · 2 √2 )
= √6(6√6)
=6 x 6 =36
4. ( √2 + √3 ) ( 5 √2 - √3 )
=5 x 2-√6+ 5√6- 3x3
=10+4√6-9
=1+4√6
5. 15 √3 - 2 √3 + 9 √13 + 3 √75
=13√3 + 9√13 + 3√75
=9√13+28√3
Semoga membantu :D
