1. The problem statement, all variables and given/known data I am working on a problem, and there is a small step I need help on: I have the expression eab, where a is a constant, and b is a variable. I need to separate a and b so I can pull out the expression b from an integral expression. Is there any exponent law or manipulation I can do algebraically that will allow me to get separate the constant a expression from the variable b expression? 2. Relevant equations Rules of exponents, algebraic manipulations. 3. The attempt at a solution There isn't any simple rule (i.e. xmxn = xm+n) that I can use to separate the two expression. I've tried moving the expression around, to no avail. Any help is appreciated!
