Power of a Product Property
[Product of Powers (Common Exponent)]
Initial Definition

If "a" and "b" are non-zero integer and "m" is a whole number, then:

Product of Powers (Common Exponent) Property

When multiplying powers with a common exponent, the result can be found by multiplying the bases and retaining the exponent.



By the symmetric property of equality, this property can be written either way.

Product of Powers (Common Base) Property

Usually it is written as shown below and is called the "power of a product" property.

Explanation        Product of Powers (Common Exponent)

2 x 3 = 6. If the unwritten exponents of one are placed in the equation, it would be written as 2131 = 61.

Notice that the exponents are all the same (one).


Divider Line

2232 = (4)(9)


2232 = 36


2232 = 62

Divider Line

2535 = (32)(243)


2232 = 7776


2232 = 65

(2x5)3 = (2x5)(2x5)(2x5)          Definition of a power


(2x5)3 = 2x5x2x5x2x5


(2x5)3 = 2x2x2x5x5x5             Rearrange   (Commutative property of multiplication)


(2x5)3 = (2x2x2)(5x5x5)


(2x5)3 = 2353
