Simplify within parentheses by combining like terms and canceling out the same variables in the numerator and denominator. For example, 4x/2x can be simplified to 2x/1.
Apply the multiplication rule to all terms in the function, wherein (b^x)(b^y) = b^(x+y).
Use the property of multiplicative distribution, wherein (ab)^x = (a^x)(b^x).
Multiply each term by the exponent.
Isolate the variable on one side to solve for x (or whatever variable is used in the equation).
