1)log(4) sinx=-1\2
log(4)sinx=-1\2 log(4) 4
log(4) sinx=log(4) 4^(-1\2)
log(4) sinx=log(4) 1\2
sinx=1\2
x=(-1)^k п/6+пn, n принадлежит Z
2)log(2x-1) 4,5x= 2log(2x-1) 2x-1
log(2x-1) 4,5x=log(2x-1) (2x-1)^2
4,5x=(2x-1)^2
4,5x=4x^2-4x+1
4x^2-8,5x+1=0
D=72,25-16=56,25
x1=(8,5+7,5)\8=2
x2=(8,5-7,5)\8=0,125
