Answer:
93/64
Step-by-step explanation:
Note: The question doesnot seem correct as the addition and multiplication signs seem to have been misplaced. But anyway following is the method
3+ sin^2 60° + cosec²30°\5+ cos²6ot sec²30°
= 3 + (√3/2)² + (2)² / 5 + (1/2)² * (2/√3)²
= 3 + (3/4 + 4) / 5 + 1/4*4/3
= 31/4 / 16/3
= 31/4 * 3/16
= 93/64.
