Expanding exponentials: expexpand

The exponential function applied to a sum can be converted into a product of exponentials; namely,

e^x+y = e^xe^y

The expexpand command does this conversion. (For expansions with other bases, see Section 6.24.6.)

expexpand takes one argument:
expr, an expression.
expexpand(expr) returns the expression expr with exponentials (base e) of sums rewritten as products of exponentials.

Example.
Input:

expexpand(exp(3*x)+exp(2*x+2))

Output:

⎛
⎝

e^x

⎞
⎠

³+

⎛
⎝

e^x

⎞
⎠
