Answer:
k = 13
Step-by-step explanation:
20 ^ k / 20^4 = 20^9
knowing the laws of exponents, diving two numbers of the same base with exponents is like subtracting the exponents, so
k^x / k^y
= k ^ (x - y)
apply that knowledge here
20 ^ k / 20 ^ 4 = 20 ^ 9
20 ^ ( k - 4 ) = 20 ^ 9
now the bases have no use here so ignore them, and just calculate the exponents
k - 4 = 9
solve using inverse operations
k - 4 = 9
+4 +4
k = 13
