🧠 Part A: Vocabulary

Match each term with its correct definition:

1. Radical
2. Index
3. Radicand
4. Square Root
5. Cube Root

Definitions:

1. The number or expression inside the radical symbol.
2. A number that, when multiplied by itself, equals a given number.
3. A quantity expressed as the root of another.
4. A number that, when multiplied by itself three times, equals a given number.
5. The number indicating which root to take.

📐 Part B: Fill in the Blanks

Complete the following paragraph with the correct terms:

The formula for the period of a pendulum, $T = 2\pi \sqrt{\frac{L}{g}}$, involves a _____. 'T' represents the _____, 'L' is the _____, and 'g' is the acceleration due to gravity. To find 'T', we need to calculate the _____ of $\frac{L}{g}$ and then multiply by $2\pi$. Understanding radical expressions helps us analyze the behavior of the _____, which has applications in fields like clock-making.
