1. Преобразуйте выражение: \( \begin{array}{ll}\text { a) }\left(\frac{1}{3} x^{-1} y^{2}\right)^{-2} ; & \text { б) }\left(\frac{3 x^{-1}}{4 y^{-3}}\right)^{-1} \cdot 6 x y^{2} \\ \text { 2. Вычислите: } \frac{3^{-9} \cdot 9^{-4}}{27^{-6}}\end{array} \)

\( x = \frac { - ( - 1 ) \pm \sqrt { - 79 } } { 2.1 } \)

November 2018 ZIMSEC Paper 1 Solve the following simultancous equations: \[ \begin{array}{l}e^{2 x+y}=1 \\ 4 x-3 y=10\end{array} \]

d the exact value of the solution to the equation \( 2 e^{2 x}-7 e^{x}-4=0 \)

2imalify \( \frac{x^{2}-y^{2}}{x^{2} x y} \) \( \frac{y+2 x-3 y}{3 x-2 y}=4 \), evaluate \( 2 x y \) If \( z=\sqrt{x^{2}-y^{2}} \), express \( x \) interm 9 \( y \) and 2

Question 8 ( 3 marks) What is the equation of the line that passes through the points \( (1,6) \) and \( (3,2) \) ? \( y=\square x+\square \)
