HISTORY of the word EXPONENT.
The term EXPONENT was introduced by Michael Stifel ( ) in 1544 in Arithmetica integra.

An exponent is simply shorthand for multiplying that number of identical factors.

So 4³ is the same as (4)(4)(4), three identical factors of 4
So 4³ is the same as (4)(4)(4), three identical factors of 4. And x³ is just three factors of x, (x)(x)(x).

Exponent is the power in an expression.

7 Laws of Exponents #1 PRODUCT LAW
To Multiply LIKE Bases… …Copy the Base, Add Exponents

Product Law or Product Rule

7 Laws of Exponents #2 QUOTIENT LAW
To Divide LIKE Bases… …Subtract Exponents a4

7 Laws of Exponents #3 EXPONENT of EXPONENT LAW
To Raise a Power to a Power… …Multiply Exponents a12

Exponent of Exponent Law or Exponential Rule:

7 Laws of Exponents #4 Raising a product to a power
To Raise a QUANTITY to a Power, raise EACH Factor to that Power. (-3ab)2= 9a2b2

7 Laws of Exponents #5 Raising a quotient or a fraction to a power
To Raise a FRACTION to a Power, raise BOTH Numerator & Denominator to that power. a4 b4

7 Laws of Exponents #6 NEGATIVE EXPONENT LAW
Negative Exponents  …Reciprocal with a Positive Exponent 1 ___ a3

#6: Negative Law of Exponents: If the base is powered by the
negative exponent, then the base becomes reciprocal with the positive exponent.

Any nonzero number raised to the ZERO Power = ONE
7 Laws of Exponents #7 Any nonzero number raised to the ZERO Power = ONE 1 1 1

The Laws of Exponents: #7: Zero Law of Exponents: Any base powered by zero exponent equals one
