Question

2^x=4^x+1

Answer 1

so the question is

\[2^x = 4^{x +1}\]

Answer 2

yeah

Answer 3

2^x = 4^(x + 1) = 2^(2x + 2)
x = 2x + 2
x = -2

Answer 4

you could make the equations in the same base. What I mean is make the 4 into a 2. :)

Answer 5

ok... so you need the same base... so 4= 2^2

so you need

\[2^x = (2^2)^{x + 1}\]

can you simplify the right hand side using the power of a power index law..?
