One thing is for certain. The final answer will be 1/r^12 or r^(-12)
When written as the given of (r^-4)^3, the powers are multiplied.
The first one is false. There are 4 factors of r^-4 If you get an answer that says it is true, then the question means that r^-4 is 3 equal factors of r^-12
B is true
C: not true. The exponents are multiplied, not added.
D is true
E: not true. This is the same thing as C.
Answer:
See explanation
Step-by-step explanation:
We want to find the value of k in

We subtract 3 from both sides;

Simplify on the right;

Square both sides;


If your equation in actually

Square both sides:
