So is that: \[log_5(4x - 7) = 2\] ?
OpenStudy (anonymous):
yes!
OpenStudy (shadowfiend):
Ok. Well, first off remember that: \[log_a b = c\] Means \[a^c = b\] So in this case we have: \[5^2 = 4x - 7\] Can you solve that?
OpenStudy (anonymous):
yes, thanx a lot!
OpenStudy (shadowfiend):
No problem :)
