Enter numbers in the colored text boxes to see how we can rewrite the same equation in different ways.

log()
log()
ba\sqrt[\alpha]{\beta} =
Smart fill mode: Smart fill updates the third variable based on the previous two values you've entered.
Note: you can type functions like sqrt and log into the textboxes, but may encounter strange behavior during the process of typing the functions in due to the way the parser works. Please report bugs to trk43@cornell.edu.
