Пошаговое объяснение:

Answer 2

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

The expression is:

(57^2 - 38^2) / (22^2 - 3^2)

Now, calculate the values:

57^2 = 57 * 57 = 3249 38^2 = 38 * 38 = 1444 22^2 = 22 * 22 = 484 3^2 = 3 * 3 = 9

Now, replace these values in the expression:

(3249 - 1444) / (484 - 9)

Now, perform the operations:

(1805) / (475)

Finally, calculate the division:

1805 / 475 ≈ 3.8

So, the result of the expression is approximately 3.8.
