2. EXPONENTIAL FORM
• Is an alternative method of expressing number.
For example:
𝑥2
, 22
, 23
, 52
3. 52 EXPONENT
BASE
Is a number which
represents the number of
times a base is to be
multiplied by itself.
Is a number which is to
be multiplied by itself
according to the
exponent.
𝟓𝟐
= 5 5 = 25
4. Law 1: Product Law
(𝑎𝑚) 𝑎𝑛 = 𝑎𝑚+𝑛
States that when multiplying two powers with the same base, just add
the exponents.
18. Law 6: Negative Exponent
𝑎−𝑛 =
1
𝑎𝑛
A nonzero base raised to a negative exponent is equal to the reciprocal
of the base raised to the positive exponent.
21. Law 1: Product Law (𝑎𝑚) 𝑎𝑛 = 𝑎𝑚+𝑛
Law 2: Quotient Law
𝑎𝑚
𝑎𝑛 = 𝑎𝑚−𝑛
Law 3: Power of a power 𝑥𝑚 𝑛 = 𝑥𝑚𝑛
Law 4: Power with different bases 𝑏𝑐 𝑛 = 𝑏𝑛𝑐𝑛 𝑎
𝑏
