The __________ is the greatest factor that divides two integers.
absolute value |
|
greatest common multiple |
|
least common multiple |
|
greatest common factor |
The greatest common factor (GCF) is the greatest factor that divides two integers.
What is (a5)5?
| a0 | |
| 5a5 | |
| a25 | |
| a10 |
To raise a term with an exponent to another exponent, retain the base and multiply the exponents:
(a5)5What is \( 2 \)\( \sqrt{48} \) + \( 8 \)\( \sqrt{3} \)
| 10\( \sqrt{3} \) | |
| 10\( \sqrt{48} \) | |
| 16\( \sqrt{3} \) | |
| 10\( \sqrt{144} \) |
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\( \sqrt{3} \)What is 6y4 + 2y4?
| 8y-8 | |
| 8y4 | |
| 4y-4 | |
| -4y-4 |
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
What is \( \sqrt{\frac{36}{25}} \)?
| \(\frac{7}{9}\) | |
| 1\(\frac{1}{5}\) | |
| 1\(\frac{1}{8}\) | |
| \(\frac{3}{4}\) |
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\(\frac{1}{5}\)
