Question

Berapa jawabannya dari persamaan logaritma ⁴log (9x+5) = 2 + ⁴log(x-1)

Answer 1

⁴log (9x+5) = 2 + ⁴log(x-1)  ⁴log nya coret
9x+5 = 2+(x-1)
9x+5 = x+1
9x-x = 1-5
8x = -4
x = -4/8
x= -1/2

Answer 2

⁴log (9x+5) = 2 + ⁴log(x-1)
⁴log (9x+5) = ⁴log 16 + ⁴log(x-1) ---> coret ⁴log
9x+5  =  16 + x -1
8x      =  10
x      =
