    well raise both sides as powers of the base remember the log law for base \[\log_{a} (a^b) = b\] then 4096 = (3x + 4)^4 now you can solve for x

    write the equation (exponential) and then look... log(3x+4)4096=4⇒(3x+4)4=4096 8^4 = 4096 => 3x+4 = 8 (base must be positive) i got the answer 4/3?

    oh I am sorry but I did also show how to solve so, if itsmichelle29 followed my steps she would have received the same answer
