Penjelasan dengan langkah-langkah:
[tex] \frac{16 \times {2}^{8} }{ {2}^{10} } [/tex]
[tex] = \frac{ {2}^{4} \times {2}^{8} }{ {2}^{10} } [/tex]
[tex] = {2}^{4 + 8 - 10} [/tex]
[tex] = {2}^{2} [/tex]
.
[tex] {( {3}^{2} )}^{ \frac{1}{2} } [/tex]
[tex] = {3}^{ \frac{2}{2} } [/tex]
[tex] = {3}^{1} [/tex]
[tex] = 3[/tex]
.
[tex] {3}^{ - 5} \times {3}^{ - 2} [/tex]
[tex] = {3}^{ - 5 + ( - 2)} [/tex]
[tex] = {3}^{ - 7} [/tex]
