Question 1

Any number to the power of 0

Answer 1

7⁰=1

Question 2

Any number to the power of -1

Answer 2

Is equal to 1 divided by the number

I.e. 10⁻¹ = 1/10

Question 3

Any number to the power of 1

Answer 3

Is equal to itself

I.e. 7¹=7

Question 4

The nth root

Answer 4

Is denoted as a¹/n and it is the number that when multiplied by itself n times in total results in a.

I.e. 9 = 9¹/₂ = √9 = 3

Question 5

Powers of powers

Answer 5

(a³)⁴ = a³ˣ⁴ = a¹²

Question 6

multiplication of powers

Answer 6

a⁴ x a⁵ = a⁴⁺⁵

Question 7

division of powers

Answer 7

a⁷ ÷ a⁵ = a⁷⁻⁵

Question 8

quotients

Answer 8

a^n/m can be interpreted as the m^th root of a^n or as the m^th root of a multiplied by itself n times

a^n/m = (m√a)^n = m√(a^n)

Question 9

Linear equations

Answer 9

y=a+bx

a is where the line cuts the y axis (intercept)

b is the gradient or slope of the line

has no powers

Question 10

Quadratic equation

Answer 10

has the form
aX^2 x bX + C

has two answers and can be solve with formula

Question 11

Manipulating inequalities

Answer 11

Are manipulated the same way as equations, except that when multiplying or dividing by a negative number you reverse the sign
