As the notation of Multiplicative group of integers modulo n I see: (Z/nZ)^x
What is this notation actually?

Z is the set of integers. nZ is the set of integer multiples of n. Z/nZ is the set of integers "modulo n". The "$$\displaystyle \times$$" superscript indicates the group operation is multiplication.
