Answer:
1/(k^2)
Step-by-step explanation:
Because the k's are above one another in the fraction format, using exponent rules you would subtract the top number exponents with the bottom number exponents (note do not do anything with the letter k). 5-7= -2, and k^-2 is the same as 1/(k^2).
Hope you have a great day and this helps! :)
