Index Laws
Simplify x0
Simplify b + b + b + b
4b
True or False? 5x + 25 can be factorised into 5(x + 5)
True or False? In the equation x+5=9, x=3
What colour was my hair at the start at the year?
Blonde
a8 ÷ a6 = a2 is an example of which Index Law? Try and describe it.
Index Law 2. When dividing the same base number, you subtract the powers.
Simplify 4y - 3y + y
2y
Name 2 common factors of 12 and 18x
1, 2, 3, 6
Solve 2(x -1) = 16
2x = 18
x = 9
What was my favourite subject at school?
Maths
Expand then simplify (53)2 using index laws.
5 x 5 x 5 x 5 x 5 x 5 = 56
Can the following expression be simplified? 3xy + 8 - xy
Yes. 2xy + 8
Simplifying x2 - 4x to x(x - 4) is an example of what?
Factorising
Solve for x. 3x-4=2
3x=6
x=2
Where was I born?
Sydney
Simplify x8 ÷ x8
Simplify 2a3 x 3ab
6a4b
Expand then simplify 4(x2 + 6) + 4x2
4x2 + 24 + 4x2
8x2 +24
Explain the steps to solve the equation 4x - 6 + 3x = 50
1. Add like terms 7x - 6 = 50
2. Add 6 to both sides of the equation 7x = 56
3. Divide by 7 on both sides x = 8
What am I afraid of?
Birds and heights
Explain why x0 = 1 in your own words
Using an example x6 ÷ x6 = x0 = 1 because 6-6=0 and therefore you are left with x to the power of zero but when dividing by the same number it always equals one.
Simplify 7x2 - y + x2 + 3z
8x2 - y + 3z
How would you factorise 2x - 10 + 18 =
2(x - 5 + 9) =
Solve 3x - 7 = 2x + 5
3x - 2x - 7 = 2x - 2x + 5
x - 7 = 5
x - 7 + 7 = 5 + 7
x = 12
