Question

Which equation demonstrates the multiplicative identity property?

Answer 1

The multiplicative identity property states that when a number is multiplied by 1, the result is the same original number.

Hence, an equation that demonstrates this property can be given as the product of any number and 1. An example for this is 100 * 1 = 100 where 100 is the original number.

Answer 2

In arithmetic., the multiplicative identity is 1. and the property is given by:

If we multiply 1 by any real number, the number stays the same i.e. 1 * a = a and a * 1 = a and this is often written as 1 * a = a = a * 1........................(*)

, where a is any real number.

(*) demonstrates the multiplicative identity property.

Note that, we can have this property in vector algebra where A*I = A, where A is any matrix and I is the identity matrix.
