Final answer:
The expression (6 x 100) + (1 x 10) + (7 x 1) + (9 x 1) + (2 x 1) equals 628 in standard form, so the correct answer is a. 61792.
Step-by-step explanation:
To evaluate the expression (6 x 100) + (1 x 10) + (7 x 1) + (9 x 1) + (2 x 1) in standard form, we perform the calculations and add the results:
(6 x 100) + (1 x 10) + (7 x 1) + (9 x 1) + (2 x 1) = 600 + 10 + 7 + 9 + 2 = 628
Therefore, the expression (6 x 100) + (1 x 10) + (7 x 1) + (9 x 1) + (2 x 1) equals 628 in standard form. Therefore, the correct answer is a. 61792.
