Step-by-step explanation:
Given that:-
sin² 30° - 2 cos³ 60° + 3 tan⁴ 45°
=>(1/2)² - 2 (1/2)³ + 3 (1)⁴
=>1/4 - 2(1/8) + 3(1)
=>1/4 - 2/8+ 3
=> 1/4-1/4+3
=>0+3
=>3

Answer:
sin²30°-2 cos³60°+3 tan⁴45°
(sin30°)²-2(cos60°)³+ 3 (tan45)⁴
(1/2)²-2(1/2)³+3(1)⁴
1/4-2×1/8+3
1/4-1/4+3
0+3
3
so the answer is 3
