Power calculation in xlsform


I am trying to calculate the two numbers multiplication in xlsform, one number is integer (120) and other one (10-6 or 106). But I can’t write (10-6 or 106) in xlsform. Also, I want to show (10-6 or 106) in the display.

I would appreciate it very much if someone can share a solution for this.

Best regards,

Welcome to the community, @probir2099! Would you mind explaining more about the 10-6 or 106 you are trying to refer to?
