Answer 1

Ответ:

x = 4

Объяснение:

$6^{x-2} - (\frac{1}{6} )^{3-x}+36^{\frac{x-1}{2} }= 246\\\\6^{x-2} - \frac{1}{6^{3-x}}+36^{\frac{x-1}{2} }= 246\\\\\frac{6-1+6^{3-x}*6^{x-1}}{6^{3-x}} =246\\\\\frac{6-1+6^{2}}{6^{3-x}} =246\\\\\frac{41}{3^{3-x}} =246\\\\246*6^{3-x} = 41|:246\\\\6^{3-x} = \frac{1}{6} \\\\6^{3-x} = 6^{-1}\\3-x = -1\\3 + 1 = x\\x = 4$
