\( x^{2}=7+4 \sqrt{3} \). (द्र) \( x \) এর মান নিণয় \( x^{6}-1 \)

4. \( \frac{(4 n)!+(4 n+1)!}{(4 n+1)!-(4 n)!} \) ifadesinin eşiti aşağıdakilerden han- gisidir? \( \begin{array}{ll}\text { A) } \frac{2 n+1}{2} & \text { B) } \frac{2 n+1}{n} \\ \text { C) } \frac{2 n+1}{2 n} & \text { D) } \frac{2 n}{2 n+1}\end{array} \)

\( 88 : 66 = 8 : \frac { } { R } \)

Question \( 7:( \) June 2023\( ) \) If \( g(x)=-x^{2}-x+5 \), then \( g(-4) \) is equal to

\( 70 : 40 = 700 : \frac { } { T } \)

\[ \frac{(2 n-3)!\cdot(3 n-3)!}{(2 n-1)!\cdot(3 n-4)!}=\frac{1}{14} \] olduğuna göre, \( n \) kaçtır?
