Expert Solution

## Answer to Problem 20E

Using Distributive property over subtraction of real numbers the expression can be written as 8a8b .

### Explanation of Solution

Given information:

An expression is given as

(ab)8

Concept used:

Distributive property over subtraction of real numbers:

Suppose a , b, and c are three real numbers, Distributive property says that

(bc)a=abac

Product of a number with a difference can be changed to difference of products.

Calculation:

Consider the expression and simplify as shown:

(ab)8=8a8b

Therefore, (ab)8 , can be written by using Distributive property over subtraction of real numbers, as 8a8b .
