5*lg2-3=lg(4x-2) решите плиииз
5lg2-3=lg(4x-2)
5lg2-lg1000=lg(4x-2)
lg32-lg1000=lg(4x-2)
lg(32/1000)=lg(4x-2)
32/1000=4x-2
4x=32/1000+2
x=2032/4000
5*lg2-3=lg(4x-2) ==> lg(2^5)-lg(4x-2)=3 ==> lg((2^5)/(4x-2))=3 ==> lg((2^5)/(4x-2))=lg1000 ==>
==> (2^5)/(4x-2)=1000 ==> (2^5)/1000=(4x-2) ==> 0,032 = 4x -2 ==> 2,032 = 4x ==>
==> x = 2,032/4 = 0.508
