Correct Answer: 4

Solution : Given, $\tan \theta+\cot \theta=2$
We know, $\cot\theta=\frac{1}{\tan\theta}$
⇒ $\tan\theta+\frac{1}{\tan\theta}=2$
⇒ $\tan^2\theta+1=2\tan\theta$
⇒ $\tan^2\theta+1-2\tan\theta=0$
⇒ $(\tan\theta-1)^2=0$
⇒ $\tan\theta-1=0$
⇒ $\tan\theta = 1$ [As $\theta$ is an acute angle]
⇒ $\cot\theta=1$
Now consider, $2 \tan ^2 \theta+\cot ^2 \theta+\tan ^4 \theta \cot ^4 \theta$
= $2\times(1)^2+1^2+(1)^4\times(1)^4$
=
