Question

What is the solution to the equation 2^(1 + 2x )= 3 ?

Answer 1

2^(1 + 2x )= 3
take the log_2 of both sides:
1+2x = log_2 3
subtract 1 from both sides:
2x = (log_2 3) - 1
divide by 2
x = [(log_2 3) - 1]/2

Answer 2

-1/2 isnt an option....

Answer 3

you didn't specify the way you wanted the solution...
and -1/2 is not what I came up with. it's
x = [(log_2 3) - 1]/2
