2. Замените значок ( \( \square \) ) так, чтобы получилось верное равенство: \( 16 \square \square \cdot \square x^{3} y=96 x^{6} y^{4} \) 3. Найипе значение выраження \( \frac{\left(5^{3}\right)^{4} \cdot 3^{6}}{15^{9} \cdot 5^{2} \cdot 3^{-4}} \) 4. Представыте выражение \( \left(a^{-6} \cdot b^{5}\right)^{3} \cdot\left(a^{8} \cdot b^{-7}\right)= \) в виде \( \mathrm{a}^{\mathrm{m}} \mathrm{b}^{\mathrm{n}} \), где m,n- целые числа

Perform the indicated operations and simplify the result. Write the exact answer, do not round, \[ (\sqrt{7}+3 \sqrt{2})^{2} \] Answer

\( 3(1-2x)<(x+1)+x-z \)

7) \( |-4-3 i| \)

99. La somma e la differenza tra le diagonali di un rombo misurano \( 9,2 \mathrm{~cm} \) e \( 2,8 \mathrm{~cm} \). L'area di un rombo simile a quello dato è \( 86,4 \mathrm{~cm}^{2} \). Calcola il rapporto tra le aree e quello tra i perimetri dei due rombi. \( \left[\frac{1}{9} ; \frac{1}{3}\right] \)
