log o podstawie 3 z 3 po potęgi (2x-1)-3log o podstawie pierwiastek z 5 z 1/5 = x * log o podstawie 1/2 z 8
log3 z 3^(2x-1) - 3log √5 z 1/5 = x * log1/2 z 8
(2x - 1) * log3 3 - 3 * log√5 z(√5)^(-2) = x * log1/2 z (1/2)^(-3)
(2x - 1) * 1 - 3 * (-2) * log√5 z √5 = x * (-3) * log1/2 z 1/2
(2x - 1) * 1 + 6 * 1 = x * (-3) * 1
2x - 1 + 6 = -3x
2x + 3x = 1 - 6
5x = -5
x = -1 ----- odpowiedź
