Answer: -1
Step-by-step explanation:
If k is equal to negative one then we can input it into it for the exponent and solve.
If multiplying exponents and they have the same base then you will just add the exponents and let the exponents stay the same.
The exponents are -3,1, and -1 add them.
-3 + 1 - 1 = -3
The base is 10 so we will raise 10 to the negative 3rd power.
