Помогите пж, желательно с фото

1,5^(5x-7) =(2/3)^(x+1) 1 1/2 ^(5x-7) =(2/3)^(x+1) (3/2)^(5x-7) = (3/2)^ -(x+1) 5x -7= - x-1 5x+x=7-1 6x=6 x=1 . 5^(x²-5x-6) =1 5^(x²-5x-6)=5^0 x²-5x-6=0 D=25+24=49=+-7² x1=(5+7)/2=6 x2=(5-7)/2= - 1 . 0.75^(2x-3) =(1 1/3)^(5-x) (3/4)^(2x-3) =(4/3)^(5-x) (3/4)^(2x-3) =(3/4)^ -(5-x) 2x-3= -5+x 2x-x=3-5 x= - 2 . (1/7)^(x²-2x-2) =1/7 (1/7)^(x²-2x-2) =(1/7)^1 x²-2x-2=1 x²-2x-3=0 D/4=1+3=4=+-2² x1=1+2=3 x2=1-2= - 1
