Answer 1

Answer:

3

Step-by-step explanation:

$\cos(0) \sin( \frac{\pi}{2} ) { \cos( { \frac{\pi}{6} } ) }^{2} { \sec( \frac{\pi}{4} ) }^{2} \\ = \: \cos(0) \sin(90) { \cos(30) }^{2} { \sec(45) }^{2} \\ = \: 1 \times 1 \times { (\frac{ \sqrt{3} }{2} )}^{2} \times {2}^{2} \\ = \: \frac{3}{4} \times 4 \\ = 3$

Hope it helps you.
