bantu dong.. jangan dihapus pertanyaan saya!! pake cara nya y

[tex]1. \: \: {3}^{ - 5} \times {3}^{3} \div {3}^{ - 4} \\ = {3}^{ - 5 + 3 - ( - 4)} \\ = {3}^{2} \\ = 9[/tex]
[tex]2. \: \: \frac{ {2}^{4} \times {2}^{2} }{ {2}^{1} \times {2}^{5} } \\ = \frac{ {2}^{4 + 2} }{ {2}^{1 + 5} } \\ = \frac{ {2}^{6} }{ {2}^{6} } \\ = {2}^{6} \times {2}^{ - 6} \\ = {2}^{0} \\ = 1[/tex]
[tex]3. \: \: (0.25)^{ - 2} \times {(0.25)}^{4} \\ = {(0.25)}^{ - 2 + 4} \\ = {(0.25)}^{2} \\ = 0.0625[/tex]
