\begin{enumerate}  \item a voltage cannot equal a voltage squared, so $V \neq <(V)^2>$ and $V_{mult} \neq (V_J + V_{\textrm{other noise}})^2>$  \item YOu should write $<(V_J)^2> + <(V_{other})^2$, not $(V_J + V_{\textrm{other noise}})^2$.  There are two independent (random) noise sources --- the resistor being measured (Johns) and the amplifier circuits (instrumentation) ---so you don't add their voltages $V_{Johnson}$ and $V_{instrumentation}$, you need to add $<(V_{\textrm{Johnson Noise}})^2>$ and $<(V_{\textrm{instrument noise}})^2>$. See textbook and manual. \item if $V_{Mult}$ means the \textit{multiplication} of two voltage signals $V_s \times V_s$ , it should be written $V^2_{mult}$  \item if $V_{Mult}$ means the voltage signal measured by a \textit{multimeter}, then it should read $V^2_{multimeter}$ = $(V_s \times V_s) / (10 \ V)$ since the output of the multiplier is divided by a 10 V reference signal before being sent to the multimeter  \end{enumerate}
