For all arbitrary set X with characteristic functions is known as fuzzy subsets. On group X, fuzzy subgroups can be formed appropriate with some axioms. In fuzzy subgroup there is sub set with some properties that known as level subgroups of fuzzy subgroup. This paper investigated the properties that exist on fuzzy subgroups. The properties associated with the image and pre-image homomorphism o…
