Real numbers are simply the combination of Whole numbers, Integers, Rational and Irrational numbers in the number system.

When two or more numbers are multiplied together, it gives a number. The numbers that are being multiplied are called the factors. And the result of the multiplication of numbers is called the product of those numbers.

Multiplicative Identity Property of Multiplication

Property: $\text{a}  ·  1  =  \text{a}$

If you multiply any real number with one (1), the product will be the original number itself.

Example: $\text{33}  ·  1  =  1  ·  \text{33}    =  33$

Name of the property for this equation $z^4  ·  1  =  z^4$is Multiplicative Identity Property of Multiplication
