tolong krjakan ya nmr 1 dan 2 pakai cara ya ,, pliz mksh

[tex] \frac{ { ({k}^{ - 8} })^{ - \frac{3}{4} } }{ {( {k}^{ - 2} })^{ \frac{ 1}{2} } } \\ = \frac{ {k}^{ \frac{24}{4} } }{ {k}^{ \frac{ - 2}{2} } } \\ = \frac{ {k}^{6} }{ {k}^{ - 1} } \\ = {k}^{6 - ( - 1)} \\ = {k}^{6 + 1} \\ = {k}^{7} [/tex]
[tex](3 \sqrt{2} + 4 \sqrt{3})( \sqrt{2} - \sqrt{3} ) \\ = 3\sqrt{4} - 3 \sqrt{6} + 4 \sqrt{6} - 4 \sqrt{9} \\ = 3(2) + 1 \sqrt{6} - 4(3) \\ = 6 + \sqrt{6} - 12 \\ = - 6 + \sqrt{6} [/tex]
Semoga dapat dipahami
