Simplify \( \sqrt{125} \)
| 8\( \sqrt{5} \) | |
| 5\( \sqrt{5} \) | |
| 9\( \sqrt{5} \) | |
| 4\( \sqrt{10} \) |
To simplify a radical, factor out the perfect squares:
\( \sqrt{125} \)
\( \sqrt{25 \times 5} \)
\( \sqrt{5^2 \times 5} \)
5\( \sqrt{5} \)
This property states taht the order of addition or multiplication does not mater. For example, 2 + 5 and 5 + 2 are equivalent.

The commutative property states that, when adding or multiplying numbers, the order in which they're added or multiplied does not matter. For example, 3 + 4 and 4 + 3 give the same result, as do 3 x 4 and 4 x 3.
What is \( \frac{1}{7} \) ÷ \( \frac{2}{8} \)?
| 1\(\frac{1}{7}\) | |
| \(\frac{4}{7}\) | |
| \(\frac{1}{12}\) | |
| 4 |
To divide fractions, invert the second fraction and then multiply:
\( \frac{1}{7} \) ÷ \( \frac{2}{8} \) = \( \frac{1}{7} \) x \( \frac{8}{2} \)
To multiply fractions, multiply the numerators together and then multiply the denominators together:
\( \frac{1}{7} \) x \( \frac{8}{2} \) = \( \frac{1 x 8}{7 x 2} \) = \( \frac{8}{14} \) = \(\frac{4}{7}\)
