Question

Solve log(3x+5) =0

Answer 1

0=log(1)

Answer 2

again if log(a)=log(b) then a=b

Answer 3

replace 0 with log(1) as suggested in my first post
and then use my second post to solve a linear equation

Answer 4

untrue

Answer 5

that is just a disguized linear equation 3x+5=1 like @freckles mentioned
log1=0
so what inside log must equal to 1 for that to happen

Answer 6

I was thinking of somthing else..

Answer 7

lol @SolomonZelman sometimes i do such mistakes hahaha

Answer 8

the other i had cal iii exam i did a severe mistake like that
hhhhhh
i know the answer yet i went for the wrong thing lol

Answer 9

the other day*

Answer 10

I overthought and started to talk nonsense

Answer 11

Okay so what do you mean? Like log3x +log5 =0..?

Answer 12

no @SPHott51

Answer 13

nn dear that is not true at all about logs

Answer 14

log(1) is 0
so replace 0 with log(1)
log(3x+5)=log(1)
implies 3x+5=1
solve 3x+5=1 for x

Answer 15

i wrote the equation above 3x+5=1

Answer 16

maybe he got confused from all the other stuff being posted about the domain versus range thing @xapproachesinfinity

Answer 17

i guess :) hopefully it is clearer now

Answer 18

though that bit is also important to know :p

Answer 19

AGHH, I always make things harder for myself

Answer 20

think of log in association with exponential
since they are inverse of each other to make your life easier

Answer 21

for instance we know that (anything)^0=1
so log1=0
it is important to understand this bond

Answer 22

for porperties of log(ab)=loga +logb
for instance came from the fact that 10^(a+b)=10^a 10^b
(im using log base 10 here, but it really does not matter for properties of logs)
