1

Which of these numbers is a factor of 24?

68% Answer Correctly
16
2
4
24

Solution

The factors of a number are all positive integers that divide evenly into the number. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24.


2

What is 4\( \sqrt{5} \) x 3\( \sqrt{7} \)?

41% Answer Correctly
12\( \sqrt{7} \)
12\( \sqrt{35} \)
7\( \sqrt{35} \)
12\( \sqrt{5} \)

Solution

To multiply terms with radicals, multiply the coefficients and radicands separately:

4\( \sqrt{5} \) x 3\( \sqrt{7} \)
(4 x 3)\( \sqrt{5 \times 7} \)
12\( \sqrt{35} \)


3

What is \( 6 \)\( \sqrt{32} \) + \( 4 \)\( \sqrt{2} \)

35% Answer Correctly
24\( \sqrt{64} \)
28\( \sqrt{2} \)
10\( \sqrt{16} \)
24\( \sqrt{16} \)

Solution

To add these radicals together their radicands must be the same:

6\( \sqrt{32} \) + 4\( \sqrt{2} \)
6\( \sqrt{16 \times 2} \) + 4\( \sqrt{2} \)
6\( \sqrt{4^2 \times 2} \) + 4\( \sqrt{2} \)
(6)(4)\( \sqrt{2} \) + 4\( \sqrt{2} \)
24\( \sqrt{2} \) + 4\( \sqrt{2} \)

Now that the radicands are identical, you can add them together:

24\( \sqrt{2} \) + 4\( \sqrt{2} \)
(24 + 4)\( \sqrt{2} \)
28\( \sqrt{2} \)


4

Which of the following is not a prime number?

65% Answer Correctly

7

5

9

2


Solution

A prime number is an integer greater than 1 that has no factors other than 1 and itself. Examples of prime numbers include 2, 3, 5, 7, and 11.


5

Which of the following statements about exponents is false?

47% Answer Correctly

b1 = 1

all of these are false

b1 = b

b0 = 1


Solution

A number with an exponent (be) consists of a base (b) raised to a power (e). The exponent indicates the number of times that the base is multiplied by itself. A base with an exponent of 1 equals the base (b1 = b) and a base with an exponent of 0 equals 1 ( (b0 = 1).
