Answer:
The first step is
Take the square root of both sides of the equation
Step-by-step explanation:
we have
Solve for x
step 1
Take square root both sides
the solutions are
and 
therefore
The first step is
Take the square root of both sides of the equation
Answer:
x = -9
Step-by-step explanation:
the equation is 2^4x = 8^x - 3.
therefore 2^4x = 2^3(x-3)
since both have powers of 2
therefore
4x = 3(x-3)
4x = 3x - 9
4x -3x = -9
x = -9
