Answer 1

Answer:

√3/2

Step-by-step explanation:

3×1/2- 4×√3/2

3/2 - 2×√3

Answer is √3/2.

Answer 2

Answer:

$\boxed{\sf{\large your \: ans \implies: \frac{ \sqrt{3( \sqrt{3} } - 4) }{2} }}$

Step-by-step explanation:

$\sf\ \: 3sin30 \degree - 4sin60 \degree \\ \\ \sf\ \implies:3 \times \frac{1}{2} - 4 \times \frac{ \sqrt{3} }{2} \\ \\ \sf\ \implies: \frac{3}{2} - \frac{4 \sqrt{3} }{2} \\ \\ \sf\ \implies: \frac{3 - 4 \sqrt{3} }{2} \\ \\ \boxed{\sf\ \implies: \frac{ \sqrt{3} ( \sqrt{3 } - 4)}{2}}$
