Question

Find the missing factor. Write your answer in exponential form.

1^9 = 1^7 • = _

Answer 1

`1^2`

Explanation:

The number 1 is called the base. When we multiply like bases, we add the exponents. So in order to get 1^9, we will multiply 1^7 by 1^2 because 7+2=9.

Answer 2

The answer is
`1^(2)`

Explanation:

Using the formula:
`a^(m)+a^(n)= a^(m+n)`

`1^(9)=1^(7)*1^(2)=1^(7+2=9) =1^(9)`
