A)

1. Perfect Square – an integer that is the square of an integer.

2. Perfect Cube – an integer that is the cube of an integer.

3. Inverse Operations – Opposite operations that “undo” each other (add/subtract, multiply/divide, square/square root, cube/cube root)

4. Base – the number that gets multiplied by itself in a power

5. Square root – a number that when multiplied by itself gives you the original number

8. Exponent – the number that tells you how many times to multiply the base times itself in a power

B) Find the perfect square that is less than the number in the square root symbol and the perfect square that is more than the number in the square root symbol. Square root the nearest perfect square to find the nearest whole number. For example, square root of 23 falls between square root of 16 and 25. It is closer to the square root of 25 which is 5.
