Question

Simplify 3a • 3b ÷ 3c ÷ 3d. The exponent on 3 is _____. (ab) ÷ (cd) (a + b) - (cd) a + b - c - d

Answer 1

a + b - c - d

Explanation:

Our expression is

`(3^a3^b)/(3^c3^d)`

Using the product of exponents, this gives us

`(3^(a+b))/(3^(c+d))\\\\=3^(a+b-(c+d))=3^(a+b-c-d)`

Answer 2

The exponent on 3 is a + b - c - d.
