Question

1 1 ------------ - ------------ ✓17 - 1 ✓17 + 1

Answer 1

$\frac{ \sqrt{17} + 1 - \sqrt{17} + 1}{( \sqrt{17} - 1)( \sqrt{17} + 1)} =$
$= \frac{2}{16} = \frac{1}{8}$

Answer 2

It seems like you've provided a mathematical expression, but it's not very clear due to the formatting. However, I'll do my best to interpret it and solve it for you.

If I understand correctly, you have the expression:

(1/√17) - (1/√17) + 1

Let's simplify it step by step:

Step 1: Combine like terms in the parentheses: (1/√17 - 1/√17) + 1

Step 2: The terms 1/√17 and -1/√17 cancel each other out, leaving us with: 0 + 1

Step 3: The result is simply: 1

So, the simplified expression is equal to 1.
