Answer 2

59²-31²=(59-31)(59+31)=28*90

77²-35²=(77-35)(77+35)=42*112

(28*90) / (42*112) = (1*90) / (42*4) = (1*15) / (7*4) = 15/28.

Answer 3

To solve this expression, you need to follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).

In your expression:

(59² - 31²) / (77² - 35²)

First, calculate the values inside the parentheses:

(59² - 31²) = (3481 - 961) = 2520 (77² - 35²) = (5929 - 1225) = 4704

Now, you can divide the two results:

2520 / 4704 ≈ 0.5357 (rounded to four decimal places)

So, the answer is approximately 0.5357.
