<PRE><B>Question 239794</B>
I got a different answer to vleith. In the question I assumed that log has a base of x? Is this incorrect?

log(base x) (3x+10) = 2   (This means what number power to base x gives 3x+10)

3x+10 = x^2

10 = x^2 - 3x 
10= (x-(3/2))^2 - 9/4
(49/4)^(1/2) = x - (3/2)
 
x = +3.5 + 3/2  OR x = -3.5 + 3/2
x = 5           OR x = -2
