Constructing a Mathematical Equation for Image Bands in Google Earth Engine

I am struggling with an equation, getting some syntax error in it, The equation is following: formula : (K2 / ln ((K1/TOA_band10)+1)) - 273.15

I am trying to do operation on image bands, but not being able to construct the right code. I have used this instead, var BT = band_10.expression((1329.24051.0/((799.02841.0/TOA_B10)+1).log10())-273.15);

but it did not work.

A general hint about constructing an equation in earth engine - javascript.

Prop `className` did not match in next js app

I have written a sample code ( Github Link here ). this is a simple next js app, but giving me error when I refresh the page. This seems to be the common problem and I tried the fix provided in the internet but does not seem to fix my issue. The error is Warning: Prop className did not match. Server: "MuiBox-root MuiBox-root-1" Client: "MuiBox-root MuiBox-root-2". Did changes for _document.js, modified _app.js as mentioned in official website and solutions in stackoverflow. but nothing seems to work. Could someone take a look and help me whats wrong with the code? Via Active questions tagged javascript - Stack Overflow https://ift.tt/2FdjaAW
