Is correct to apply the next boolean algebra rule?
No. It is not correct. 

Not for any special case or exception, but for the very simple reason that the negation of the terms has been carried out improperly.

\$ \overline{A\bar{B}E} = \bar{A} + B + \bar{E} \$

Which is clearly not the same thing as:

\$ \bar{A}B\bar{E} \$

But I simply don’t understand these questions. Verifying the result is much easier and faster than typing the question in MathJax. 

Just write down the 8-row truth table for the expression. If it is = 1 it would be rather obvious from there. You would see that it’s not, even before you write the second row down.
