arindaaristiani 5. $\frac{5a ^{ \frac{1}{4} } - 2b ^{ \frac{2}{3} } }{a ^{ \frac{1}{2} } }$
= $\frac{5(2 ^{4})^{ \frac{1}{4} } - 2 (3 ^{3}) ^{ \frac{2}{3} } }{(2 ^{4}) ^{ \frac{1}{2} } }$
= $\frac{5 . 2 - 2 . 9}{4}$
= $\frac{10-18}{4}$
= $\frac{-8}{4}$ = -2

6. 16 $\frac{1}{3}$ × 0,5 $\frac{1}{3}$ × 4
= ( 16 × 0,5 ) $\frac{1}{3}$ × 4
= $8^{ \frac{1}{3} }$ × 4
= 2 × 4 = 8

7. 2 √75 - 5 √27 + √48 - 3 √12
= 2 . 5 √3 - 5 . 3 √3 + 4 √3 - 3 . 2 √3
= 10 √3 - 15 √3 + 4 √3 - 6 √3 = - 7 √3
