[tex]b)( - \frac{2}{9} {)}^{8} \div ( - \frac{2}{9} {)}^{6} = ( - \frac{2}{9} {)}^{8 - 6} = ( - \frac{2}{9} {)}^{2} [/tex]
[tex]c) {40}^{6} \div {40}^{0} = {40}^{6} \div 1 = {40}^{6} [/tex]
[tex]d) {8}^{7} \div 8 = {8}^{7 - 1} = {8}^{6} [/tex]
[tex]e) {6}^{9} \div {6}^{9} = {6}^{9 - 9} = {6}^{0} = 1[/tex]
