Is 7, 849 a reasonable answer for 49 x 49? why or why not?

This answer is not reasonable.

Step-by-step explanation:

If we do mental math, and calculate 49 x 49 we can see that the last digits to be multiplied are both 9. And 9 x 9 = 81

So, there must be a 1 at the ones place in the final answer.

But here it is given that 49 x 49 = 7849 that is totally wrong.

Moreover the tens place numbers are both 4 so 4 x 4 = 16 and the number at the starting can be near 16 and not 78.

So, this is not reasonable at all.
