Homework Statement
(4x)^(1 + log(base 2) (x)) = 8(x^3)
What is the sum of the values of x that fullfill that equation?
A) 2.5
B) 2.0
C) 1.5
D) 1.0
E) 0.5
Homework Equations
Use the exponential equation only and make the lower one (exponented) 1.
The Attempt at a Solution
(4x) = (2 x^(1/2))^2
8(x^3) = (2x)^3
If I insert x = (1/4) to make 4x = 1 it doesn't fulfill the equation..
So does x = (1/2)..
I cannot simplify the exponential equation... Any assistance please?
