tolongg dong..besok mau dikumpul..

[tex]7.) \\ (64 {}^{ \frac{1}{2} } ) {}^{ \frac{1}{3} } \\ = (8 {}^{2 \times \frac{1}{2} } ) {}^{ \frac{1}{3} } \\ = 8 {}^{ \frac{1}{3} } \\ = 2 {}^{3 \times \frac{1}{3} } \\ = 2[/tex]
☛️ Jadi, jawabannya A.

[tex]8.) \\ \frac{3}{5 - \sqrt{3} } \\ = \frac{3}{5 - \sqrt{3} } \times \frac{5 + \sqrt{3} }{5 + \sqrt{3} } \\ = \frac{3(5 + \sqrt{3} )}{25 - 3} \\ = \frac{15 + 3 \sqrt{3} }{22} [/tex]
☛️ Jadi, jawabannya A.

7. 64^(1/2))^(1/3)
=8^(1/3)
=2

8. 3/(5 - akar 3)
= 3 (5 + akar 3) / (25 - 3)
= (15 + 3 akar 3)/22


maaf kalo salah ya
