Homework Statement
Solve the equation:
2^x multiplied by 4^(x + 5) = 4^(2x - 1)
Homework Equations
The Attempt at a Solution
2^x multiplied by 2^2(x+5)=2^2(2x-1)
x(2x+10)=4x-2
2x^2+10x=4x-2
and that's as far as i could get before I was completely stuck. But this could be...

Solve the equation:
(1/9)^m = 81^m + 4
Homework Equations
I know how to do a similar equation:
9^2p = 27^p-1
3^4p = 3^3p-1
cancel out the 3's because the base is the same.
4p = 3p-1
-3p -3p
1p = -1
The Attempt at a Solution
I know how to do ones...
