7th grade / Number / Powers & Roots / Indices / Convert exponents to expanded form
An exponent is a number raised to a power. 2³ is an exponent as is 4⁴. In 2³, the number 2 is called the base and the ³ is the power.
The expanded form of an exponent is the base multiplied by itself the number of times indicated by it's power.
For example: 3³ (exponent) = 3 x 3 x 3 (expanded form)
To derive the expanded form from the exponent, lay out the base multiplied by itself the number of times indicated by the power. Here are some examples:
8³ (exponent) = 8 x 8 x 8 (expanded form)
11⁴ (exponent) = 11 x 11 x 11 x 11 (expanded form)
21⁵ (exponent) = 21 x 21 x 21 x 21 x 21 (expanded form)
To derive the exponent from the expanded form, take the number being multiplied as the base, and use the number of times it has been multiplied as the power. Here are some examples:
6 x 6 (expanded form) = 6² (exponent)
7 x 7 x 7 (expanded form) = 7³ (exponent)
4 x 4 x 4 x 4 (expanded form) = 4⁴ (exponent)
In this topic you are asked to convert in both directions between exponents and the expanded form of exponents.
With our Four in a row math game you will be practicing the topic "Convert exponents to expanded form" from 7th grade / Number / Powers & Roots / Powers & Roots. The math in this game consists of 16 questions that ask you to convert between base with exponent and expanded form e.g. 3³ <=> 3 x 3 x 3.
The game will reinforce the math you have chosen to learn by getting you to match the question to the correct answer.
