nilai dari (81) 3/4 + 16 3/4 dibagi (125) 2/3 - (27) 2/3

[tex] 81^{ \frac{3}{4} } = (3^{ 4})^{ \frac{3}{4} } } = 3^{3} [/tex]
[tex]16^{ \frac{3}{4} } = (2^{ 4})^{ \frac{3}{4} } } = 2^{3}[/tex]
[tex]125^{ \frac{2}{3} } = (5^{ 3)^{ \frac{2}{3} } } = 5^{2}[/tex]
[tex]27^{ \frac{2}{3} } = (3^{ 3)^{ \frac{2}{3} } } = 3^{2}[/tex]

[tex] \frac{ 3^{3} + 2^{3} }{ 5^{2} - 3^{2} } = \frac{27+8}{25-9} = \frac{35}{16} [/tex]

2] (81^(3/4) + 16^(3/4)) / (125^(2/3) - 27^(2/3))
= (27 + 8) / (25 - 9)
= 35/16

jawabnnya B

3] ((3√5) / (√2 + √6))
= (3√5) x (√2 - √6) / (√2² - √6²)
= (3√10 - 3√30) / (2 - 6)
= (3√10 - 3 √30)/-4
= (3/4) √30 - (3/4)√10

jawabannya C
