Comments & Wishes ⇒ I'm new with LaTex. Hoping someone may be able to help me

Hi, I was wondering if someone could help me write this equation in LaTex. Thanks.
x=2(2^{(a-1)/2} +2^{(a+1)/2})-4.
To make sure it makes sense, it's 2 x (2 to the (a-1)/2 power + 2 to the (a+1)/2 power) -4.
In other words, if a=5, it would be 2 x ( 2^2+2^3)-4.
Hope that makes sense.
Thank you very much,
Gary

Hi Gary,

welcome to the forum!

This would be the LaTeX code:

Code: Select all

\[
  x = 2 \left(2^{\frac{a-1}{2}} + 2^{\frac{a+1}{2}}\right) - 4
\]

Would you like to learn LaTeX? An excellent quick start is LearnLaTeX.org, see for example the Math Lesson.
