Define exponents
|
Exponents refers how many the number is to be multiplied itself.
Example: 3^3 = 3 x 3 x 3 |
|
What if exponent is 0? example 3^0
|
3^0 = 1
|
|
What if exponent is negative?
example 3^-3 |
3^-3 = 1 / 3^3
|
|
What if exponent is fraction?
example 3^4/3 |
3^4/3 = 3 power to 4 and then square root of 3
|

=
a^(n + m) |
|
Law of Exponents
(a x b)^3 |
=
a^3 x b^3 |
|
Law of Exponents
(a^m)^n |
=
(a)^(m x n) |
|
Law of Exponents
(a^n / b^n) |
=
(a / b)^n |
|
Law of Exponents
(a^m) / (a^n) |
=
a^ (m-n) |

How to multiply two factors eg. (3x^2 + 4xy)x(5x + 3y^4)
|
=
3x^2 ( 5x + 3y^4)+ 4xy (5x + 3y^4) or 5x (3x^2 + 4xy) + 3y^4 (3x^2 + 4xy) |
|
