Question

(-2/7]^-6 / [-2/7]^4 is equal to :​

Answer 1

$\frac{ {( \frac{ - 2}{7} )}^{( - 6)} }{ {( \frac{ - 2}{7} )}^{(4)} } \\ \\ \huge \boxed{ = > \frac{ {a}^{m} }{ {a}^{n} } \: \: \: = {a}^{m - n} }\\ \\ \\ = > { \bigg( \frac{ - 2}{7} \bigg)}^{ - 6 - 4} \\ \\ \\ = > { \bigg( \frac{ - 2}{7} \bigg)}^{ - 10} \: \: = { \bigg( \frac{7}{ - 2} \bigg)}^{10} \\ \\ \\ = > { \bigg( \frac{ -7}{2} \bigg)}^{10}$
