Question 970484
Consider the equation log(3x-1)=(log_2)8. Explain why 3x-1 is not equal to 8. Describe the steps you would take to solve the equation, and state what 3x-1 is equal to.
-------------
log(3x-1) is base 10
If you mean {{{log(2,8)}}} that's a different base, base 2.
----
You might recognize that {{{log(2,8) = log(2,2^3) = 3}}}
If not, use the base change {{{log(2,8) = log(8)/log(2) = 3}}}
----------------
Either way, log(3x-1) = 3
log(3x-1) = log(10^3) = log(1000)
3x-1 = 1000
x = 1001/3
