-----
Solve for x given 16^x-5*8^x=0
(Please help me solve this question) - equations are solved. Questions are answered.
=================
16^x - 5*8^x = 0
---
(2^4)^x - 5*(2^3)^x = 0
2^(4x) - 5*2^(3x) = 0
2^(3x)*(x - 5*2) = 0
---
2^(3x) = 0 ------- not possible for real values of x
or
(x - 5*2) = 0
x - 10 = 0
x = 10
