Practice Math TEAS TEST

1. What is any number raised to the power of zero?

Correct answer: A

Rationale: The correct answer is A: One. Any number raised to the power of zero is always equal to 1. This is a fundamental property of exponentiation. Choice B, 'Itself,' is vague and does not specify a numerical value. Choice C, 'Zero,' is incorrect as any nonzero number raised to the power of zero is 1, not 0. Choice D, 'Two,' is incorrect as any number raised to the power of zero is 1, not 2.

2. Which of the following choices best describes the location of the trachea in relation to the esophagus?

Correct answer: B

Rationale: The trachea is situated in front of the esophagus, making it anterior to the esophagus. This anatomical relationship is crucial to understand in clinical practice, particularly regarding airway management and esophageal intubation. Therefore, the correct answer is B: 'Anterior.' Choices A, C, and D are incorrect because the trachea is not located to the side (lateral), behind (posterior), or on the back (dorsal) of the esophagus.

3. A ball is thrown upwards. Which of the following statements is TRUE about its potential energy and kinetic energy at the peak of its trajectory?

Correct answer: B

Rationale: At the peak of its trajectory, the ball momentarily stops moving before falling back down. This means its kinetic energy is at a minimum because it has come to a stop. At the same time, its potential energy is at a maximum because it is at the highest point in its trajectory, where it has the most potential to fall and convert that potential energy into kinetic energy as it descends. Choice A is incorrect because at the peak, the ball still has potential energy due to its height. Choice C is incorrect because kinetic energy is at a minimum when the ball is momentarily at rest. Choice D is incorrect because the energy conversion between potential and kinetic energy occurs at different points in the trajectory.

4. Which of the following sentences contains a homophone?

Correct answer: C

Rationale: The correct answer is C. 'Raze' is a homophone of 'raise,' which means to destroy completely. The other choices do not contain homophones. Choice A talks about a young woman walking on a canal path, choice B discusses water heating up and expanding, and choice D mentions a previous tenant who was a chemistry teacher, none of which involve homophones. Therefore, choice C is the only sentence that contains a homophone, making it the correct answer.

5. The student studies diligently for her upcoming exam. Which word is the plural form of 'study'?

Correct answer: C

Rationale: In this context, 'study' is a verb, not a noun. 'Studied' is the past tense form of the verb 'study.' The plural form of a verb does not exist in the same way as it does for nouns. 'Studied' is the correct form for the past tense of 'study,' not a plural form. 'Studies' (choice A) is the third-person singular present tense form of 'study,' 'studying' (choice B) is the present participle form, and 'studier' (choice D) is not a correct form related to the verb 'study.' Therefore, 'studied' is the most appropriate choice here.
