I don't quite understand your problem ,but, those are variables.. so what you have written makes no sense, and without any other signs (+,*,/) which shows you means 1*1*1*1, if you could explain this in more detail i would appreciate it!
Ok so u know to divide bc u r trying to isolate the variable and that means undoing the function in this case 0.6 is multiplied to p so u do the opposite which is division
