B 1/7^2

D 7^-10 / 7^-8

Step-by-step explanation:

7^-2

We know that a^-2 = 1/a^2

1/7^2 = 1/49

We also know that anything with a power of 2 in the denominator is good

7^-8 / 7^-10 = 7^2  

7^-10 / 7^-8 = 7^-2 = 1/7^2 = 1/69  that is the second answer

Step-by-step explanation:

Answers C and D are correct.  

Note that in C we have    7^(-8)

                                          ,  

                                          7^(-10)

which is equivalent to 7^(-8 + 10), or 7^2, or 49.
