m=\operatorname{cosec} \theta-\sin \theta

and

n=\sec \theta-\cos \theta

, then

\mathrm{m}^{2 / 3}+\mathrm{n}^{2 / 3}=

View answer and explanation

Correct option: A

(\mathrm{mn})^{-2 / 3}

Option C (

(mn)^{-2 / 3}

) is correct because simplifying the expressions for m and n and then substituting them into the target expression yields the result.
