<prompt> Kutokana na integer n, kurudi kweli kama ni uwezo wa nne. vinginevyo, kurudi uongo. Integer n ni uwezo wa nne, kama kuna integer x kama vile n 4x.  <response>: To check if an integer n is a power of four, we can take the logarithm base 4 of n and check whether the result is an integer. If it is an integer, then n is a power of four.Here is a Python code that implements this logic:pythonimport mathdef is_power_of_fourn: if n 0: return False x math.logn, 4 return x intxThe function takes an integer n as input and first checks if n is less than or equal to 0. If it is, then n cannot be a power of four.Next, it calculates the logarithm base 4 of n using the math.log function. If the result is an integer, then n is a power of four and the function returns True. Otherwise, it returns False.For example, is_power_of_four16 would return True because 16 is equal to 42.
