The exponent form of 6 x 6 x 6 is 6^{3}. There are two parts to exponent notation:

1. the base and

2. the exponent.

The base tells you what number is being multiplied and the exponent tells you how many times this number is used as a factor. In the above example the base is 6 and the exponent is 3.

**CUBE**

When the exponent is 3 the result is called the cube. To cube a number, we use the number in a multiplication 3 times. For example, 2 cubed means 2×2×2 which is 8. We can write 2 cubed as 2^{3}, 5 cubed (5^{3}) would be 5×5×5 = 125. You also have an **x ^{3}** button on your calculator to speed up cubing. Find it and use it. See the practice problems.

**CUBE ROOT **

A cube root is exactly the opposite direction. For instance, the cube root of 8 is 2. The symbol used for cube root is:

#####
\[\sqrt[3]{ }\]

The cube root of 8 can be written as:

** Finding the Cube root**

How do you find the cube root of any number? Using a calculator is the easiest way.

Find out where the

#####
\[\sqrt[3]{ }\]

button is on your calculator and whether it is a second function **(2ndF)** or not. Find it and use it. See the practice problems.

Get a $20-or-so dual-display scientific calculator, even if you can`t take it with you into the exam hall. A calculator is also a learning tool, Technology Use is one of the 9 Essential Skills you can`t do without. Trying out different functions on a calculator will further your understanding and help with building a bigger mental picture. It builds links between numbers and algebra. It is important to try alternative calculations or approaches, to sketch & label angles, tracking changes to units of measure, visualizing to cross-link the concepts of volume and numbers.
