No. 1
[tex] \tt = {5}^{ - 1} - {5}^{0} [/tex]
[tex] \tt = \frac{1}{5} - 1[/tex]
[tex] \tt = \frac{1}{5} - \frac{5}{5} [/tex]
[tex] \tt = - \frac{4}{5} [/tex]
No. 2
[tex] \tt = { \frac{1}{3} }^{ - 2} \div {3}^{ - 2} [/tex]
[tex] \tt = { ({3}^{ - 1}) }^{ - 2} \div {3}^{ - 2} [/tex]
[tex] \tt = {3}^{2} \div {3}^{ - 2} [/tex]
[tex] \tt = {3}^{2 - ( - 2)} [/tex]
[tex] \tt = {3}^{2 + 2} [/tex]
= 3⁴
= 81
No. 3
[tex] \tt = {2}^{ - 5} \times { \frac{1}{2} }^{ - 8} \div {5}^{ - 2} [/tex]
[tex] \tt = {2}^{ - 5} \times { ( {2}^{ - 1} )}^{ - 8} \div {5}^{ - 2} [/tex]
[tex] \tt = {2}^{ - 5} \times {2}^{8} \div {5}^{ - 2} [/tex]
[tex] \tt = {2}^{ - 5 + 8} \div {5}^{ - 2} [/tex]
[tex] \tt = {2}^{3} \div \frac{1}{ {5}^{2} } [/tex]
[tex] \tt = 8 \div \frac{1}{25} [/tex]
[tex] \tt = 8 \times \frac{25}{1} [/tex]
