Answer :
Suppose that n and a are two real and integers.
We have then that we can rewrite an expression of the form:
[tex] n * a [/tex]
As the sum of "a" times "n".
For example:
For n = 4 and a = 3 we have:
[tex] 4 * 3 = 12 [/tex]
Equivalently we have:
[tex] 4 * 3 = 4 + 4 + 4 = 12[/tex]
We have then that we can rewrite an expression of the form:
[tex] n * a [/tex]
As the sum of "a" times "n".
For example:
For n = 4 and a = 3 we have:
[tex] 4 * 3 = 12 [/tex]
Equivalently we have:
[tex] 4 * 3 = 4 + 4 + 4 = 12[/tex]
Answer:
Equivalent expression for n x a = a+ a+a+a....n times
Step-by-step 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.
