Question

(7/4m^-2)^2

Quiero saber si la respuesta es: 49/16m4

Answer 1

$\left (\dfrac{7}{4m^{-2}}\right) ^{2}= \\ \\ \\ \left (\dfrac{7^{2} }{(4m^{-2})^{2} }\right) = \\ \\ \\ \left (\dfrac{49 }{(4 ^{2} m^{-4}) }\right) = \\ \\ \\ \left (\dfrac{49 }{(16 m^{-4}) }\right) = \boxed{\left (\dfrac{49m ^{4} }{16 }\right) }$

Espero que te sirva, salu2!!!!
