Answer 1

$14.a) {17}^{2} \div ( - 17) {}^{2} = {17}^{2} \div {17}^{2} = 1$

$b)( - 25) {}^{3} \div ( - 5) {}^{3} = - 25 {}^{3} \div ( - 5) {}^{3} = {5}^{6} \div {5}^{3} = {5}^{3}$

$c)( - 361) {}^{2} \div 19 {}^{2} = 361 {}^{2} \div 19 {}^{2} = 19 {}^{4} \div 19 {}^{2} = 19 {}^{2}$

$d)(324) {}^{2} \div ( - 18) {}^{2} = {18}^{4} \div {18}^{2} = {18}^{2}$

$e)(1331) {}^{3} \div ( - 121) {}^{3} = 1331 {}^{3} \div ( - 121 {}^{3}) = - 11 {}^{9} \div {11}^{6} = - 11 {}^{3}$

$f)(123) {}^{15} \div ( - 123) {}^{15} = {123}^{15} \div ( - {123}^{15}) = - 1$
