Do one of the following programming problems:
Power Function
  Create a function called compute_power(base, exponent),
  which
  recieves two parameters: a floating point value representing the
  base of the
  power, and an integer representing the exponent.  Your function
  should
  return a floating point value representing the result of raising the
  base to
  the specified exponent.  Your function should not use the **
  operator. 
Recall that exponentiation is:
$$ b^n = \underbrace{b \times b \times \ldots \times b}_{n} $$
Where there are \(n\) occurances of \(b\) in the terms on the right hand side of the equation.
Geometric Series
  Create a function called geometic_series(num_terms)
  that computes the sum of the specified number of terms of the series:
$$1 + \frac{1}{2} + \frac{1}{4} + \frac{1}{8} + \frac{1}{16} + \ldots$$
