Answer 1

xlog(4) (5 - x) - 2.5log(4) (x - 5)^2 = 0

одз  5 - x > 0

x < 5

xlog(4) (5 - x) - 2.5log(4) (x - 5)^2 = 0

xlog(4) (5 - x) - 2.5*2 log(4) |x - 5| = 0

xlog(4) (5 - x) - 5 log(4) (5 - x) = 0

(x - 5)log(4) (5 - x) = 0

x - 5 = 0   x = 5 нет x < 5

log(4) (5 - x) = 0

5 - x = 1

x = 4

ответ 4
