PLEASE HELP !!!!!!

Answer 1

Answer:

$\frac{1}{ \sqrt[7]{ {12}^{4} } }$

Step-by-step explanation:

${12}^{ - \frac{4}{7} } is \: the \: same \: as \\ \frac{1}{ {12}^{ \frac{4}{7} } } \\ {12}^{ \frac{4}{7} } can \: also \: be \: expressed \: as \\ \sqrt[7]{ {12}^{4} }$

Therefore:

${12} ^ { -\frac{4}{7} } \: is \: equivalent \: to \\ \frac{1}{ \sqrt[7]{ {12}^{4} } }$
