Which of the following numbers is largest in value? (All angles are given in radians.)

\(\tan\left(\frac{5\pi}{4}\right)\),

\(\sin^2 \left(\frac{5\pi}{4}\right)\),

\(\log_{10} \left(\frac{5\pi}{4}\right)\),

\(\log_2 \left(\frac{5\pi}{4}\right)\).

Which of the terms can we evaluate exactly? How do the other terms compare?
