Question: If $\cot \,\theta +\tan \theta =m$and $\sec \theta -\cos \theta =n,$then which of the following is correct

1) $m{{(m{{n}^{2}})}^{1/3}}-n{{(n{{m}^{2}})}^{1/3}}=1$

2) $m{{({{m}^{2}}n)}^{1/3}}-n{{(m{{n}^{2}})}^{1/3}}=1$

3) $n{{(m{{n}^{2}})}^{1/3}}-m{{(n{{m}^{2}})}^{1/3}}=1$

4) $n{{({{m}^{2}}n)}^{1/3}}-m{{(m{{n}^{2}})}^{1/3}}=1$
