Question

Find an expression equivalent to the one shown below.913 x 9-6OA. 79OB.919OC. 97OD. 9-78

Answer 1

C. 9⁷

Step-by-step explanation:

We will use the following property of the exponents:

`x^a* x^b=x^(a+b)`

It means that when we have the same base, we can simplify the expression by adding the exponents. So, in this case, the equivalent expression is:

`9^(13)*9^(-6)=9^(13-6)=9^7`

Therefore, the answer is C. 9⁷
