Question

solve log2(3x+1)=4

Answer 1

transform it into an exponential equation

Answer 2

how do i do that?

Answer 3

log2(3x+1)=4 means that:
10^4=2(3x+1)

Answer 4

@luisrock2008 is that:
\[
\log_2(3x+1)=4\\ \text{or}\\ \log2(3x+1)=4?

\]

Answer 5

d91196 where do you get the 10 from

Answer 6

@nbouscal its the first one

Answer 7

If the 2 was for log base 2 then:
then:
2^4=3x+1

Answer 8

Okay, \(\log_2(3x+1)=4\) means: \(2^4=3x+1\). That you can solve by just calculating \(2^4\) and then solving normally.

Answer 9

You ok from there?
