I need to calculate the rank of the matrix A, shown below:

$$\left[\begin{array}{ccc}3& 2& -1\\ 2& -3& -5\\ -1& -4& -3\end{array}\right]$$

You can still ask an expert for help

Simply use row reduction: the rank is the number of non-zero rows after you've performed row reduction:

Find the exact value of each logarithm without using a calculator.

$\mathrm{ln}e}^{3$

Break up the following function using laws of logarithms, then compute the derivative. $f\left(x\right)=\mathrm{ln}\left(\frac{6(x+1)}{{x}^{3}}\right)$

What is wrong with this solution?

$\mathrm{ln}\left(x\right)=1+\mathrm{ln}\left(5\right)$

$x={e}^{1+\mathrm{ln}\left(5\right)}={e}^{1+5}={e}^{6}$

What exactly am I doing wrong here?

Mean Value theorem problem?(inequality)

I'm trying to solve this mean value theorem problem but confused where to start,

If $0<a<b$ prove that $(1-\frac{a}{b})<\mathrm{ln}\frac{b}{a}<\frac{b}{a}-1$

Can someone please lend me a hand?
