Answer:

Equivalent expression for n x a = a+ a+a+a....n times

Explanation:

Given: Expression for n x a .

To find : Write an equivalent expression for n x a using only addition.

Solution : We have given that n x a .

Here, we can say Sum of a is n times.

We can rewrite it n x a = a+ a+a+a....n times.

Example : 3 x 2 = 2 +2+ 2.

6 = 6 ( true)

Therefore , equivalent expression for n x a = a+ a+a+a....n times.

Suppose that n and a are two real and integers.
We have then that we can rewrite an expression of the form:

n * a
As the sum of "a" times "n".
For example:
For n = 4 and a = 3 we have:

4 * 3 = 12
Equivalently we have:

4 * 3 = 4 + 4 + 4 = 12
