Missing simplifications

[holgerengels]

Description

Some expected simplifications are not applied

Steps to Reproduce

1. a^n·a^m = a^{n+m)

ce.parse("e^xe^x").simplify()
produces: ["Power","ExponentialE",["Multiply",2,"x"]] .. which is correct

ce.parse("e^{2x}e^x").simplify()
produces: ["Multiply",["Power","ExponentialE","x"],["Power","ExponentialE",["Multiply",2,"x"]]] .. which is unexpected
expected: ["Power","ExponentialE",["Multiply",3,"x"]]

2. \frac{a^n}{a^m} = a^{n-m)

ce.parse("\\frac{e^x}{e^x}").simplify()
produces: ["Divide",["Power","ExponentialE","x"],["Power","ExponentialE","x"]] .. no simplification takes place
expected: "1"
