Definition Of Power Properties

Power of a Power Property: This property states that the power of a power can be found by multiplying the exponents.
That is, for a non-zero real number a and two integers m and n, (am)n = amn.

Product of Powers Property: This property states that to multiply powers having the same base, add the exponents.
That is, for a real number non-zero a and two integers m and n, am × an = am+n.
Quotient of Powers Property: This property states that to divide powers having the same base, subtract the exponents.
That is, for a non-zero real number a and two integers m and n,Power Properties .

Power of a Product Property: This property states that the power of a product can be obtained by finding the powers of each factor and multiplying them.
That is, for any two non-zero real numbers a and b and any integer m, (ab)m = am × bm.

Power of a Quotient Property: This property states that the power of a quotient can be obtained by finding the powers of numerator and denominator and dividing them. That is, for any two non-zero real numbers a and b and any integer m,.
