Using \sqrt in the denominator of the \frac command [closed]

Question

Below is the following code that I am trying to use in math mode. When I do this it distorts the sqrt line and blends into the fraction line.

z=$\frac{ Estimate_{t} - Estimate_{t-1}} \sqrt{Var_{t} + Var_{t-1}}$

I don't know if it is a spacing issue with the \frac command or if I am missing a { some place.

Any help would be appreciated.

The answer is given already but that input must have generated an error message, something like ! Missing { inserted. <to be read again> } l.20 ...frac{ Estimate_{t} - Estimate_{t-1}} \sqrt If you get an error message from tex any output you get is essentially arbitrary accidental recovery, so don't look at the spacing before fixing the error. — David Carlisle, Jun 4, 2013 at 1:24

The \frac{}{} command uses two pairs of braces:

$z=\frac{Estimate_{t} - Estimate_{t-1}}{\sqrt{Var_{t} + Var_{t-1}}}$

Please read some basic material such as the LaTeX Wikibook.
