For this case we have the following expression:

Rewriting the expression we have:

In the division, if we have the same base, the exponents are subtracted.
Therefore, by rewriting the expression we have:
Answer:
The equivalent expression is given by:
Answer:

If you are trying to simplify or isolate the variables, its 4. Please tell me if this answer is wrong
Let us determine the product of 438 and 17 by partial products.
Consider 
and 
So, 

= 
= 7446
Therefore, the product of 438 and 17 is 7446.
No, Sandra's answer is not correct.
Because she should have expressed 17 as (10+7), then if she multiplied (438 by 10) and (438 by 7). And, then added the results.Then her answer would be correct.
