Explanation:
Let's calculate the expression:
57 x 57 + 43 x 43 + 2 x 57 x 43
Using the order of operations (PEMDAS/BODMAS), we first perform the multiplications:
57 x 57 = 3249
43 x 43 = 1849
2 x 57 x 43 = 4886
Now, add these results together:
3249 + 1849 + 4886 = 9984
So, the output of the expression is 9984.
None of the options provided match this result exactly, but the closest option is D. 1000. However, the correct answer should be 9984, not 1000.
