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.
[tex]10^{-3} * 10^{1} * 10^{-1}[/tex] 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.
[tex]10^{-3}[/tex]
