Question 562263: I'm having trouble solving this problem log 2x =-1. Can you give me an example of a problem close to this one? Answer by issacodegard(60) (Show Source):
You can put this solution on YOUR website! Hi, let say that log_b is the logarithm with base b function.
Solve log_2(3y+1)=6 for y
We have,
log_2(3y+1)=6
2^(log_2(3y+1))=2^(6) (exponentiate with respect to the base 2)
3y+1=64
3y=63
y=21
Note that log_b(x) and b^x are inverse functions, so b^(log_b(x))=x
