Find the algebraic form of the following complex number.
\[
5\left (\cos \frac{3\pi }
{4} + \mathrm{i}\sin \frac{3\pi }
{4}\right )
\]
\(-\frac{5\sqrt{2}}
{2} + \mathrm{i}\frac{5\sqrt{2}}
{2} \)
\(\frac{5\sqrt{2}}
{2} -\mathrm{i}\frac{5\sqrt{2}}
{2} \)
\(\frac{5}
{2} + \mathrm{i}\frac{5}
{2}\)
\(\frac{5}
{2} -\mathrm{i}\frac{5}
{2}\)
