[tex]5. \: {a}^{ - 2} \div {a}^{ - 3} = {a}^{ - 2 - ( - 3)} \\ = {a}^{ - 2 + 3} \\ = {a}^{1} [/tex]
[tex]6. \: {a}^{ - 3} \div {a}^{ - 2} = {a}^{ - 3 - ( - 2)} \\ = {a}^{ - 3 + 2} \\ = {a}^{ - 1} [/tex]
[tex]7. {( {a}^{ - 3} )}^{ - 2} = {a}^{ - 3. ( - 2)} \\ = {a}^{6} [/tex]
[tex]8.{( {a}^{ - 2} )}^{ - 3} = {a}^{ - 2.( - 3)} \\ = {a}^{6} [/tex]
[tex]9. {(ab)}^{ - 3} = {a}^{ - 3} {b}^{ - 3} [/tex]
