How to do this in latex [duplicate]

Question

How to write this formula:

How can I read symbol e?

Welcome to TeX.SX! You can have a look at our starter guide to familiarize yourself further with our format. I think you need \hat{e} but you chose the worst title possible. — CarLaTeX, Jul 7, 2018 at 7:20
Please clarify what you mean by "read symbol e"? Are you asking how to place a "hat" symbol above a lowercase letter "e"? — Mico, Jul 7, 2018 at 7:25
Did you see the posting Trying to use “\~” to generate tilde symbol in math mode? This answer addresses not only to tilde symbols, but "hat", "dot", "double-dot" and other symbols as well. — Mico, Jul 7, 2018 at 7:33

coding:

$\hat{e}(aP,bP)= \hat{e}(P,bP)^a$

Did you mean to write bP instead of p?

-1: Answers should be self-contained, i.e. one can copy, paste and typeset them without having to write boilerplate. Please make your answer into a minimal working example (MWE).

+1 The question itself is lacking a MWE, so it would be unfair to expect a MWE in an answer

I would recommend to use \left and \right as well

\hat{e}\left(aP,bP\right) = \hat{e}\left(P,bP\right)^a

For such simple expression, I would not recommend. Maybe \bigl( \bigr). But this is just opinion.

@Sigur Actually, according to this question, this answer and this answer, \left and \right should be used sparsely.

Useful insights about the \left and \right commands. Thank you.
