Property 7           (ab)ⁿ = aⁿbⁿ

 

By Property 7 we can take a product then the power or take the powers then the product.

 

Examples

          (4x)³ = (4x)(4x)(4x) = (4 · 4 · 4) (x · x · x) = 4³x³ = 64x³

 

It is not true that (a + b)ⁿ = aⁿ + bⁿ. This mistake is very common.

 

Property 8           

 

Property 8 says that we can take the quotient first then the power or each power followed by the quotient.
