# Help! Double superscript

What is the problem?

\displaystyle \prod_{i=1}^{n} {\beta}{\alpha}(1 - e^{- (x - \mu)\beta}^{\alpha -
1}e^{- (x - \mu)\beta}


I've been trying to change {\beta}{\alpha} and (1 - e^{- (x - \mu)\beta}^{\alpha - 1}

• It would help if you copied the actual error message, but I think it's complaining about e^{}^{}. (Also, you can use backticks to typeset code, and {\beta} doesn't do anything useful. Jul 30 '18 at 12:53
• Double superscript. l.160 ...{\beta}{\alpha}(1 - e^{- (x - \mu)\beta}^ {\alpha - 1}e^{- (x - \mu)... Jul 30 '18 at 12:55

$\prod_{i=1}^{n} {\beta}{\alpha}(1 - e^{{- (x - \mu)\beta}^{\alpha - 1}}e^{- (x - \mu)\beta}$
