5 cos^2 60° + 4 sec^2 30° - tan^2 45°÷ sin^2 30° + cos^2 30°
= 5 (1/2)^2 + 4 (2/root3)^2 - tan (1)^2 ÷ (1/2)^2 + (root 3 / 2)^2
= 5 (1/4) + 4 (4/3) - 1 ÷ 1/4 + (3/4)
= 5/4 + 16/3 - 1 ÷ 4/4
= 15/12 + 64/12 - 1/12
= 78/12
= 26/4
= 5 (1/2)^2 + 4 (2/root3)^2 - tan (1)^2 ÷ (1/2)^2 + (root 3 / 2)^2
= 5 (1/4) + 4 (4/3) - 1 ÷ 1/4 + (3/4)
= 5/4 + 16/3 - 1 ÷ 4/4
= 15/12 + 64/12 - 1/12
= 78/12
= 26/4
