I need help. I need to write these equations in LaTeX, I wrote it like this:


   (x^{\alpha})' \ = \ \alpha x^{\alpha -1}, \ \alpha \in \mathbb{R}, \ x \in 

   (\log_a{x})' \ = \ \frac{1}{x}\log_a{e}, \ x>0 \\

to get the numbers on the right side. I also have a Section so if I use align he automatically put number 2.3 which I don't need enter image description here

    I think you should rather use \begin{align} ...\end{align} instead of such \begin{equation}...\end{equation} wrapper. equation itself is numbered already, so there is no need to number it again with a different counter, in my point of view. – user31729 Apr 5 '17 at 14:14
  • it is myequation because i need to have D.24 if i put only equation it will be numbered as 1 – Ana Leko Apr 5 '17 at 14:20

    You could as well set equation to 23 – user31729 Apr 5 '17 at 14:24

In most cases such wrapper environments are not really well-designed and the alignment can be done with align as well.




(x^{\alpha})'  &=  \alpha x^{\alpha -1}, \,\alpha \in \mathbb{R}, \, x \in 
\mathbb{R} \\
(\log_a{x})'  &=  \frac{1}{x}\log_a{e}, \,x>0
