What is 9z5 + z5?

66% Answer Correctly
10z25
8z5
10z5
8z-5

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:

9z5 + 1z5
(9 + 1)z5
10z5


2

What is \( 9 \)\( \sqrt{8} \) + \( 9 \)\( \sqrt{2} \)

35% Answer Correctly
81\( \sqrt{4} \)
27\( \sqrt{2} \)
18\( \sqrt{2} \)
18\( \sqrt{8} \)

Solution

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

9\( \sqrt{8} \) + 9\( \sqrt{2} \)
9\( \sqrt{4 \times 2} \) + 9\( \sqrt{2} \)
9\( \sqrt{2^2 \times 2} \) + 9\( \sqrt{2} \)
(9)(2)\( \sqrt{2} \) + 9\( \sqrt{2} \)
18\( \sqrt{2} \) + 9\( \sqrt{2} \)

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

18\( \sqrt{2} \) + 9\( \sqrt{2} \)
(18 + 9)\( \sqrt{2} \)
27\( \sqrt{2} \)


3

What is \( \sqrt{\frac{25}{16}} \)?

70% Answer Correctly
\(\frac{5}{6}\)
1\(\frac{1}{4}\)
1
1\(\frac{1}{6}\)

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:

\( \sqrt{\frac{25}{16}} \)
\( \frac{\sqrt{25}}{\sqrt{16}} \)
\( \frac{\sqrt{5^2}}{\sqrt{4^2}} \)
\( \frac{5}{4} \)
1\(\frac{1}{4}\)


4

How many 10-passenger vans will it take to drive all 67 members of the football team to an away game?

80% Answer Correctly
7 vans
11 vans
13 vans
5 vans

Solution

Calculate the number of vans needed by dividing the number of people that need transported by the capacity of one van:

vans = \( \frac{67}{10} \) = 6\(\frac{7}{10}\)

So, it will take 6 full vans and one partially full van to transport the entire team making a total of 7 vans.


5

The __________ is the smallest positive integer that is a multiple of two or more integers.

56% Answer Correctly

absolute value

greatest common factor

least common factor

least common multiple


Solution

The least common multiple (LCM) is the smallest positive integer that is a multiple of two or more integers.
