Step-by-step explanation:

Take the natural log of both sides:

$ln ({x}^{y} ) = ln ({y}^{x} )$

Logarithm rules allow you to bring down the exponents:

$yln(x) = xln(y)$

Now differentiate. We will have to implicitly differentiate 'y' since it is a function of 'x'. Both sides require the product rule:

$\frac{dy}{dx} ln(x) + \frac{y}{x} = ln(y) + \frac{x}{y} \frac{dy}{dx}$

Isolate the terms that have y' since that is what we want:

$\frac{dy}{dx} ln(x) - \frac{x}{y} \frac{dy}{dx}= ln(y) - \frac{y}{x}$

Factor out y' to get:

$\frac{dy}{dx}( ln(x) - \frac{x}{y})= ln(y) - \frac{y}{x}$

Therefore:

$\frac{dy}{dx} = \frac{ln(y) - \frac{y}{x} }{ln(x) - \frac{x}{y} }$

PLSSS HELP IF YOU TURLY KNOW THISS

Answer:

0.143

Step-by-step explanation:

First of all, you're gonna need to know decimal places

0.143

0=ones

1=tenths

4=hundreths

3=thousandths

So now you know that you need to go to the third decimal place

To get your answer you need to divide your numerator (top number) by your denominator (bottom number)

1÷7=0.14285714

You round up the 2 to a 3 because when rounding you take the closest number that isn't being used and if its larger than 5 then you can round up your number

Lastly, you put your answer in the thousandths decimal place

There ya go! Your answer is 0.143
