Answer:

The slogan "Nike Just Do It" primarily uses an emotional appeal as a persuasive technique. It is a motivational statement that aims to inspire people to take action towards achieving their goals, without providing any logical or factual evidence to support the claim that the Nike brand can help them achieve it.

The slogan appeals to the emotional desires and needs of the consumers, such as the desire for self-improvement, success, and accomplishment. By using a concise, powerful and memorable slogan, Nike is trying to create an emotional connection between the consumers and the brand, and to influence their behavior and decision-making process.

Therefore, while the statement may be effective in creating an emotional connection with consumers, it does not rely on faulty logic or unsupported facts to persuade its audience. Instead, it is primarily an emotional appeal that aims to motivate and inspire people towards achieving their goals, and to associate the Nike brand with these feelings of motivation and success.
