Question of the Day

Link to the question!

The question of the day has continued! This set of the questions can be answered within the following week!

Hello, everyone!

I am Blueeighthnote, and I will be responsible for the questions for this week's questions. The following questions can be answered until August 14, 12:00 pm (UTC).

After the retirement of 3primetime3, the founder of "Question of the Day!", the feature has been absent for half a year......but don't worry! The questions will now be continued......starting now!

Questions

We will start with some easy ones this week:

1. Multiple choices: Which of the following numbers are rational? [25 points]

A. 3.1416
B. √3
C. log₁₀√5 + log₁₀√2
D. $\dfrac{\sin15^\circ}{\cos15^\circ}$ + $\dfrac{\cos15^\circ}{\sin15^\circ}$
E. The only real root to the following expression: x³ - 2² + x - 1 = 0.

2. Explain why 0.9999999..... = 1. Any proving method is allowed; however, each person answering must use a different method to prove it. [40 points.]

3. In an exam, where all 17 questions are made up of single-choice questions. There are 5 options in each question, while only one of them is correct. If the student answers them in a completely random fashion, what is the chance for all 17 questions to be correct? This question does not need to be converted into pure numbers: just simply express it in its simplest form. [40 points]
