Question

Solve the equation: 3^x+1=1/9

Answer 1

you realize that 3^0 is 1 and 1/9 is 3^-2

Answer 2

3^x+3^0=3^-2

Answer 3

3^x+1=1/3^2
3^x+1=3^-2
x+1=-2
x=-3

Answer 4

oh is it 3^(x+1)?
no wonder, i was getting worried there

Answer 5

Acually im not sure but two answers better than one right?

Answer 6

nah, 3^0 doesn't work out

Answer 7

that would be unsolvable

Answer 8

Or it can be solved by log
Log(3^x)+log(1)=log(3^-2)
xlog3+log1=-2log3
Xlog3=-2log3-log1
X=(-2log3-log1)/log3

Answer 9

don't think you can do that
log(3^x+1) is not log(3^x)+log(1)

Answer 10

you take the log of both sides, not individual expressions

Answer 11

Hmmm... Will it does has something wrong but cant find it
