que- 3 solve the following​

Answer 1

$(( - \frac { 1}{3} )^{8} \div ( - \frac { 1}{3} ) ^{5} ) - (( - \frac { 1}{3} ) ^{5} \div ( - \frac { 1}{3} )^{3} ) \\ = ( - \frac { 1}{3} ) ^{8 - 5} - ( - \frac { 1}{3} ) ^{5 - 3} \\ = ( - \frac { 1}{3} ) {}^{3} - ( - \frac { 1}{3} ) {}^{2} \\ = \frac{ - 1}{27} - \frac{1}{9} \\ = \frac{ - 1 - 3}{ 27} \\ = \frac{ - 4}{27}$

Hope it helps you.. thanks
