Mathematics Questions

a) If \( x \in \mathbb{Z} \), \( x < \sqrt{29} < x + 1 \), what is the value of \( x \)?

(a) 4

(b) 5

(c) 6

(d) 7

😊 TRUE: The correct answer is (b) 5. Since \( \sqrt{25} = 5 \) and \( \sqrt{36} = 6 \), we have \( 5 < \sqrt{29} < 6 \), so \( x = 5 \).

b) Estimating \( \sqrt[3]{25} \) to the closest integer is ……….

(a) 2

(b) 3

(c) 5

(d) 12.5

😊 TRUE: The correct answer is (c) 5. Since \( 2^3 = 8 \) and \( 3^3 = 27 \), \( \sqrt[3]{25} \) is closer to 3 than to 2.

😞 FALSE: Please try again.

c) Which of the following numbers is an irrational number that lies between 2 and 3?

(a) \( 2.5 \)

(b) \( \sqrt[4]{10} \)

(c) \( \sqrt[3]{6.25} \)

(d) \( \sqrt[3]{\frac{9}{9}} \)

😊 TRUE: The correct answer is (b) \( \sqrt[4]{10} \). Since \( 2^4 = 16 \) and \( \sqrt[4]{10} \) is approximately 1.78, which is between 2 and 3.

😞 FALSE: Please try again.
