( 1/ √2) ^ 3x+4 = (2√2)^x решить уравнение
( 1/ √2)^3x+4 = (2√2)^x (√2^-1)^(3x+4)=(√2^3)^x -3x-4=3x 6x=-4 x=-2/3 ----------------------
( 1/ √2) ^ 3x+4 = (2√2)^x (√2^-1) ^ 3x+4 = (√2^2 √2)^x (√2) ^ -(3x+4) = (√2)^3x -(3x+4) = 3x -4 = 6x x = - 2/3 проверка ( 1/ √2) ^ (3*(-2/3)+4) = (2√2)^(-2/3) (2√2)^(-2/3) = (2√2)^(-2/3)
