E'zozadagi stikerlarning \( \frac{3}{5} \) qismi Barnodagi stikerlardan ikki baravar ko'p. E'zozada Barnodagiga qaraganda 56 ta ko'p stiker bor. a) E'zozadagi stikerlar sonining Barnodagi stikerlar soniga nisbatini toping. b) Barnoda nechta stiker bor?

\( \left\{\begin{array}{l}\text { Реши систему неравенств: } \\ (5 x+10)-5 \cdot(x+5)>5 x \\ (x-3)(x+8)<0\end{array}\right. \)

Solve the exponential equation: \( 3^{2x} = 81 \)

VII. Find the solution(s) of the following system. \[ \left\{\begin{array}{r}x_{1}+x_{2}+x_{3}+x_{4}=0 \\ 2 x_{1}+2 x_{2}+3 x_{3}+4 x_{4}=0 \\ 2 x_{1}+2 x_{2}+2 x_{3}+2 x_{4}=0 \\ 3 x_{1}+3 x_{2}+4 x_{3}+5 x_{4}=0\end{array}\right. \]

100. यदि \( 5^{\sqrt[3]{x}}+12^{\sqrt[3]{x}}=13^{\sqrt[3]{x}} \) है, तो \( x \) का मान है: If \( 5^{\sqrt[3]{x}}+12^{\sqrt[3]{x}}=13^{\sqrt[3]{x}} \), then the value of \( x \) is:

(3) If the point \( (x-5,7-x) \) lies in the second quadrant, then \( x=- \) \( \begin{array}{lll}\text { (a) } 9 & \text { (b) } 3 & \text { (c) } 7\end{array} \)
