\frac{4\left(\cos 75^{\circ}+i \sin 75^{\circ}\right)}{04\left(\cos 30^{\circ}+i \sin 30^{\circ}\right)}

View answer and explanation

Correct option: A

\frac{10}{\sqrt{2}}(1+i)

Option A (

\frac{{10}}{{\sqrt{{2}}}}(1+i)

) is correct because after simplifying using trigonometric identities, the expression equals

\frac{{10}}{{\sqrt{{2}}}}(1+i)
