Answer 1

Ответ:

a² = 2

Объяснение:

$\displaystyle \left \{ {{a^3b=4^8} \atop {ab=8^5}} \right. \left \{ {{a^3b=2^{16}} \atop {ab=2^{15}}} \right. \left \{ {{\displaystyle \frac{a^3*2^{15}}{a}=2^{16} } \atop {b= \displaystyle \frac{2^{15}}{a}\hfill }} \right. \left \{ {{a^2=\displaystyle \frac{2^{16}}{2^{15}} } \atop { \displaystyle b=\frac{2^{15}}{a}\hfill}} \right. \quad \Rightarrow\quad a^2=2$
