About :
numpy.log10(arr, out = None, *, where = True, casting = 'same_kind', order = 'K', dtype = None, ufunc 'log10') : This mathematical function helps user to calculate
Base-10 logarithm of x where x belongs to all the input array elements.
Parameters :
array : [array_like]Input array or object.
out : [ndarray, optional]Output array with same dimensions as Input array,
placed with result.
**kwargs : allows you to pass keyword variable length of argument to a function.
It is used when we want to handle named argument in a function.
where : [array_like, optional]True value means to calculate the universal
functions(ufunc) at that position, False value means to leave the value in the
output alone.
Return :
An array with Base-10 logarithmic value of x;
where x belongs to all elements of input array.
Code 1 : Working
Output :
Input array : [1, 3, 5, 100000000]
Output array : [ 0. 0.47712125 0.69897 8. ]
np.log10(4**4) : 8.0
np.log10(2**8) : 8.0
