1

The __________ is the greatest factor that divides two integers.

67% Answer Correctly

absolute value

greatest common multiple

least common multiple

greatest common factor


Solution

The greatest common factor (GCF) is the greatest factor that divides two integers.


2

What is (a5)5?

80% Answer Correctly
a0
5a5
a25
a10

Solution

To raise a term with an exponent to another exponent, retain the base and multiply the exponents:

(a5)5
a(5 * 5)
a25


3

What is \( 2 \)\( \sqrt{48} \) + \( 8 \)\( \sqrt{3} \)

35% Answer Correctly
10\( \sqrt{3} \)
10\( \sqrt{48} \)
16\( \sqrt{3} \)
10\( \sqrt{144} \)

Solution

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

2\( \sqrt{48} \) + 8\( \sqrt{3} \)
2\( \sqrt{16 \times 3} \) + 8\( \sqrt{3} \)
2\( \sqrt{4^2 \times 3} \) + 8\( \sqrt{3} \)
(2)(4)\( \sqrt{3} \) + 8\( \sqrt{3} \)
8\( \sqrt{3} \) + 8\( \sqrt{3} \)

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

8\( \sqrt{3} \) + 8\( \sqrt{3} \)
(8 + 8)\( \sqrt{3} \)
16\( \sqrt{3} \)


4

What is 6y4 + 2y4?

66% Answer Correctly
8y-8
8y4
4y-4
-4y-4

Solution

To add or subtract terms with exponents, both the base and the exponent must be the same. In this case they are so add the coefficients and retain the base and exponent:

6y4 + 2y4
(6 + 2)y4
8y4


5

What is \( \sqrt{\frac{36}{25}} \)?

70% Answer Correctly
\(\frac{7}{9}\)
1\(\frac{1}{5}\)
1\(\frac{1}{8}\)
\(\frac{3}{4}\)

Solution

To take the square root of a fraction, break the fraction into two separate roots then calculate the square root of the numerator and denominator separately:

\( \sqrt{\frac{36}{25}} \)
\( \frac{\sqrt{36}}{\sqrt{25}} \)
\( \frac{\sqrt{6^2}}{\sqrt{5^2}} \)
\( \frac{6}{5} \)
1\(\frac{1}{5}\)
