How do you find the derivative of f(x)=x^(-9/7)?
1 Answer
Dec 5, 2016
Use the power rule: $\frac{d}{\mathrm{dx}} \left({x}^{p}\right) = p {x}^{p - 1}$
Explanation:
$f ' \left(x\right) = - \frac{9}{7} {x}^{- \frac{9}{7} - 1} = - \frac{9}{7} {x}^{- \frac{16}{7}}$ | HuggingFaceTB/finemath | |
# How do you solve ln(x-2)^2=6?
##### 1 Answer
Aug 15, 2016
We will solve for $x$ using the very basic properties of natural logarithms. I'll illustrate it below.
#### Explanation:
We have, $L n {\left(x - 2\right)}^{2} = 6$
Using the property, $L n {m}^{n} = n L n m$,
We have, $L n {\left(x - 2\right)}^{2} = 6$
