$2\mathrm{.}17$ LAB: Musical note frequencies

On a piano, a key has a frequency, say f$0.$ Each higher key $($black or white$)$ has a frequency of f$0*$ 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 $3$ higher key frequencies.

Output each floating$-$point value with two digits after the decimal point, then the units $("$Hz$"),$ then a newline, using the following statement:

print$($f$\text{'}\{$your$\_$value:$\mathrm{.}2$f$\}$ Hz$\text{'})$

Ex: If the input is:

$440$

$($which is the A key near the middle of a piano keyboard$),$ the output is:

$440\mathrm{.}00$ Hz

$466\mathrm{.}16$ Hz

$493\mathrm{.}88$ Hz

$523\mathrm{.}25$ Hz

Note: To compute the next $3$ higher key frequencies, use one statement to compute r $=2(1/12)$ using the pow function $($remember to import the math module$).$ Then use that r in subsequent statements that use the formula fn $=$ f$0*$ rn with n being $1,2,$ and finally $3$
