## ammu123 2 years ago find the derivative of y with respect to x, t or theta as appropriate. y= ln(x)/x^6

1. DisplayError

$y=(x^{-6})*\ln x$ Use the product rule (derivative with respect to x) $y'=(x^{-6})*(\frac{1}{x})+(\ln x)*(-6x^{-7})$

2. ammu123

the answer is 1-7 ln(x)/ x^7 how can u get that?

3. DisplayError

Simplify from what I typed and you should get the exact same answer. Remember that $x^{-a} = \frac{1}{x^a}$
