Answer:

$-\frac{ln(662)-2}{4}$

{-1.12}

Step-by-step explanation:

$e^{2 - 4x} = 662$

Solve this exponential equation using natural log

Take natural log ln on both sides

$ln(e^{2 - 4x}) = ln(662)$

As per the property of natural log , move the exponent before log

$2-4x(ln e) = ln(662)$

we know that ln e = 1

$2-4x= ln(662)$

Now subtract 2 from both sides

$-4x= ln(662)-2$

Divide both sides by -4

$x=-\frac{ln(662)-2}{4}$

Solution set is { $x=-\frac{ln(662)-2}{4}$ }
