Game: DUCK SHOOT
Aim: Shoot as many ducks as you can
Method:
Use the catapult to shoot balls at the rows of ducks crossing the screen. Answer questions to win extra points.
Your final score is based on ducks hit or missed and the number of questions answered correctly.
8th grade / Number / Powers & Roots / Indices / Divide 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.
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 Duck shoot 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.
DUCK SHOOT is a fun game to learn math where you attempt to knock over all the fairground ducks in each level. In the first level there are only 6 ducks but by level 10 there are 24 fast moving "quackers quacking"...
After each level, win an additional 20 points by correctly answering a math question from your selected topic. There is no timer in this game: take as long as you like to answer the math questions correctly for a best score to get you on the DUCK SHOOT leaderboard.
