Solve the following exponential equation by taking the natural logarithm on both sides. Express the solution in terms of natural

Cloud [144]

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

USe calculator to find decimal approximation

x=-1.12381x=-1.12

I understood the whole problem but why they add 5 under square root?<br>please help me

mash [69]

I don't understand.. but I think that I know why.. just give me a little more details about the question but here's my guess.:

It may be square root like the answer may be squared in order to answer a rectangular prism..

Or, it may be a power..

Sorry, I don't know if I was helping, but this is the best I could do b/c I don't know a lot about the problem
