# Complex analysis 1/(z-w)^4

## Main Question or Discussion Point

Oh god, so confused and panicked today
I know this is a very basic question, but, givin the function 1/(z-w)^4

does this have one pole of order 4, or possibly 4 poles of order 1...???

''to get the zero's of a function, set the numerator = 0''
''to get the poles of a function, set the denominator = 0''
is this correct??
