tolong dibantu ya pakai cara nomer 2& 4

No. 3
[tex] \sqrt[3]{ {a}^{2} } \times a \sqrt[4]{ {a}^{3} } \\ {a}^{ \frac{2}{3} } \times a \times {a}^{ \frac{3}{4} } \\ {a}^{ \frac{17}{12} } \times a \\ a \times a \times {a}^{ \frac{5}{12} } \\ {a}^{2} \sqrt[12]{ {a}^{5} } [/tex]

[tex] \sqrt[2]{p} \times \sqrt[2]{ {16}^{n} } = \sqrt[2]{32} \\ {( \sqrt[2]{p} \times \sqrt[2]{ {16}^{n} } = \sqrt[2]{32} )}^{2} \\ p \times {16}^{n} = 32 \\ p = 2 \\ n = 1[/tex]
