${\huge{\pink{\underline{\underline{Formula\ used}}}}}$

${(a+b)}^{3}={a}^{3}+{b}^{3}+3{a}^{2}b+3a{b}^{2}$

${\huge{\pink{\underline{\underline{SoLuTiOn}}}}}$

${(2+\sqrt{3})}^{3}={2}^{3}+{\sqrt{3}}^{3}+(3×{2}^{2}×\sqrt{3})+(3×2×{\sqrt{3}}^{2})\\</p><p>=>8+\sqrt{27}+3×4×\sqrt{3}+3×2×3\\</p><p>=>8+3\sqrt{3}+12\sqrt{3}+18\\</p><p>=>8+18+3\sqrt{3}+12\sqrt{3}\\</p><p>=>26+15\sqrt{3}\ is\ answer..$
