Multiplying Exponential Expressions

7.1 Multiply (7x+2y) by (7x+2y)

The rule says : To multiply exponential expressions which have the same base, add up their exponents.

In our case, the common base is (7x+2y) and the exponents are :

1 , as (7x+2y) is the same number as (7x+2y)1

and 1 , as (7x+2y) is the same number as (7x+2y)1

The product is therefore, (7x+2y)(1+1) = (7x+2y)2

Final result :

7a2b2c2 • (7x - 2y) • (7x + 2y)2
