Question

4(sin⁴30° + cos⁴60°)​

Answer 1

Answer:

$\huge\sf\red{Answer}$

4 ( sin⁴30° + cos⁴60°)

• sin 30° = ½

• cos 60° = ½

➡️ 4 × ( ½⁴ + ½⁴)

➡️ 4 × 1/16 + 1/16

➡️ 4 × 2/16

➡️ 8/16

➡️ 1/2

Answer 2

Step-by-step explanation:

4(sin^430°+cos^460°)

=4[(1/2)^4+(1/2)^4]

=4(0.0625+0.0625)

=4×0.125

=0.5
