1Which of the following numbers is an irrational number?

A.0.333...

B.√7

C.-5/8

D.√16

Explanation: An irrational number cannot be expressed as a ratio of two integers. √7 cannot be simplified to a whole number or fraction because 7 is not a perfect square, so its decimal expansion is non-terminating and non-repeating. 0.333... = 1/3 (rational), -5/8 is a ratio of integers (rational), and √16 = 4 (rational).

2Which statement correctly describes the decimal expansion of a rational number?

A.It is always non-terminating and non-repeating.

B.It must terminate or repeat eventually.

C.It can never be written as a fraction.

D.It always contains the symbol π.

Explanation: By definition, every rational number can be written as a fraction a/b (where a and b are integers and b ≠ 0), and its decimal expansion either terminates (like 0.75 = 3/4) or repeats infinitely (like 0.666... = 2/3). Non-terminating and non-repeating decimals are irrational.

3Between which two consecutive integers does √50 lie on a number line?

A.5 and 6

B.6 and 7

C.7 and 8

D.8 and 9

Explanation: Identify the perfect squares surrounding 50: 49 < 50 < 64. Taking square roots gives √49 < √50 < √64, which simplifies to 7 < √50 < 8. Therefore, √50 lies between 7 and 8 (approximately 7.07).

4Simplify the expression 3⁴ × 3² using exponent rules.

A.3⁶

B.3⁸

C.9⁶

D.9⁸

Explanation: When multiplying expressions with the same base, keep the base and add the exponents: 3⁴ × 3² = 3⁴⁺² = 3⁶.

5Simplify the expression (4³)².

A.4⁵

B.4⁶

C.4⁹

D.16⁶

Explanation: When raising a power to a power, keep the base and multiply the exponents: (4³)² = 4³ˣ² = 4⁶.

6Simplify 5⁸ / 5³.

A.5⁵

B.5¹¹

C.5²⁴

D.1⁵

Explanation: When dividing expressions with the same base, keep the base and subtract the exponent in the denominator from the exponent in the numerator: 5⁸⁻³ = 5⁵.

7Write 520,000 in scientific notation.

A.52 × 10⁴

B.5.2 × 10⁵

C.5.2 × 10⁻⁵

D.0.52 × 10⁶

Explanation: Scientific notation is written as a × 10ⁿ, where 1 ≤ a < 10 and n is an integer. Move the decimal point 5 places to the left to get 5.2, so 520,000 = 5.2 × 10⁵.

8Convert 4.1 × 10⁻⁴ to standard form.

A.0.00041

B.0.0041

C.0.041

D.-41,000

Explanation: A negative exponent of -4 means moving the decimal point 4 places to the left: 4.1 → 0.41 → 0.041 → 0.0041 → 0.00041.

9Evaluate √144.

A.12

B.72

C.14

D.24

Explanation: The principal square root of 144 is the non-negative number that, when squared, equals 144. Since 12 × 12 = 144, √144 = 12.

10Evaluate ∛64.

A.4

B.8

C.16

D.21.33

Explanation: The cube root of 64 is the number that, when cubed (multiplied by itself three times), equals 64. Since 4 × 4 × 4 = 64, ∛64 = 4.
