I have the following equation (as you can see I have used split
):
\begin{equation}\label{testequation}
\begin{split}
d_{m}^{\phi}\left(A,f\right)=\sqrt[m]{\mid A\left(pi\right)-f\left(pi\right)\mid^{4}+\sum_{i=1;i\neq pi}^{length\left(R\right)}\mid M\left(i\right)- \\ f\left(i\right)\mid^{7}}
\end{split}
\end{equation}
I want this part of the equation to be on a new line:
-f\left(i\right)\mid^{7}
And, as you can see, I have used \\
. But, it didn't work, although I have used the same method for another formula in the same LaTex
document and it worked.
What would be the issue here?
Thanks.
