<u>Answer:</u>
Multiplicative identity of 1
<u>Explanation:</u>
We have an expression . If this expression is
multiplied by 1, we get a result same as the given expression i.e.
.
It means that the number 1 multiplied with the expression had no effect on it as we got the same expression.
This is called the multiplicative identity of 1 according to which any time you multiply a number by 1, the result or the product is that original number.
