On a piano, a key has a frequency, say f0. Each higher key (black or white) has a frequency of f0 * rn, where n is the distance (number of keys) from that key, and r is 2(1/12). Given an initial key frequency, output that frequency and the next 4 higher key frequencies. Ex: If the input is 440 (the A key near the middle of a piano keyboard), the output is: 440 466.1637615180899 493.8833012561241 523.2511306011974 554.3652619537443 Note: Use one statement to compute r = 2(1/12). Then use that r in subsequent statements that use the formula fn = f0 * rn with n being 1, 2, 3, and finally 4. Note: Import the math module as part of your code to help you compute r = 2(1/12)
