'Divide Indices' for 8th grade
8th grade / Number / Powers & Roots / Indices / Divide Indices
Divide indices with the same base by subtracting powers
What are indices?
Indices are terms that have been raised to a power such as 5⁶ or y⁴. This means the term has been multiplied by itself that number of times.
6⁴ = 6 x 6 x 6 x 6 and y⁵ = y x y x y x y x y
So the term indice simply means a number or term raised to a power.
How to divide indices with the same base
Indices with the same base can be divided by subtracting powers. So a³ and a⁶ have the same base "a", but x³ and y⁶ do not have the same base and cannot be simplified by subtracting powers.
To understand why dividing indices with the same base involves subtracting powers, consider x⁷ ÷ x⁴. If we expand both indices we get:
x x x x x x x x x x x x x
x x x x x x x
Since we know that x divided by x is 1, we can cancel terms top and bottom to simplify the expression leaving x x x x x.
x⁷ ÷ x⁴ = x³
So we can see that dividing x⁷ by x⁴ gives us x³. In general, you can divide indices with the same base by subtracting the powers.
If one or more of the terms is raised to a negative power, you should follow simple arithmetic rules to subtract the powers.
p⁻⁵ ÷ p³ = p⁻⁸
p⁻⁵ ÷ p⁻³ = p⁻²
If there are coefficients in front of the bases, divide the coefficients first and then subtract the powers.
15p⁵ ÷ 3p³ = 5p⁵
With our Sow grow math game you will be practicing the topic "Divide Indices" from 8th grade / Number / Powers & Roots / Powers & Roots. The math in this game consists of 16 questions that ask you to divide indices with the same base by subtracting powers e.g. 6b⁵ ÷ 2b² = 3b³.
Sow grow is a gentle game that concentrates on your ability to answer math questions. The game itself is very simple to play and does not require manual dexterity or fast reaction times. You are growing sunflowers in pots on a window sill. When you answer questions correctly you get to pick a sunflower to put in the vase. When the vase is full, you have completed the game.
