$e^{4 x - 1} = {(e^{2})}^{x}$

Step 1

Apply the power rule and multiply exponents, ${(a^{m})}^{n} = a^{m n}$ .

$e^{4 x - 1} = e^{2 x}$

Step 2

Since the bases are the same, then two expressions are only equal if the exponents are also equal.

$4 x - 1 = 2 x$

Step 3

Solve for $x$ .

Step 3.1.1

Subtract $2 x$ from both sides of the equation.

$4 x - 1 - 2 x = 0$

Step 3.1.2

Subtract $2 x$ from $4 x$ .

$2 x - 1 = 0$

Step 3.2

Add $1$ to both sides of the equation.

$2 x = 1$

Step 3.3

Divide each term in $2 x = 1$ by $2$ and simplify.
