Question

Solve log5x = log (2x+9)

Answer 1

5x = 2x+ 9 simply..isnt it ?

Answer 2

\[5x=2x+9\]

Answer 3

5x-2x=9
3x=9
x=3

Answer 4

Simple.

Answer 5

You would disregard the logs..?

Answer 6

actually, you should tak Anti log both the side. so it will ultimately 2 simple equation. as I explained already.

Answer 7

@4meisu If log A = log B, then A = B

Answer 8

unless 5 was the base...

Answer 9

that's a different story

Answer 10

u can only discard if the base of the log is the same..here the base of both the log in 10..tht is default

Answer 11

@lgbasallote Please clarify why the deduction "If log A = log B, then A = B" is not true for any base of the logs (with the condition that the same base is used on each side of the equation).

Answer 12

i was referring to the question

Answer 13

this is true if the base of the logs r same..hn A=B..or else not

Answer 14

could have just been copy-pasted thus failed to show that 5 is the base

Answer 15

the question could have been this \[\huge \log_5 x = \log (2x+9)\]

Answer 16

@lgbasallote You are right. The original question could well have been as you point out.
