Answer:
m=3, n = 7
Explanation:
Assuming m and n are integers, the following are the possible values of m and n
Let m = 1, then m³ = 1 and n= 189
If m = 2 we get 8n = 189 and 189/8 is not an integer so m ≠ 2
If m = 3, we get 27n = 189 and n = 189/27 = 7
Any higher integer values of m will not result in n being an integer and I am assuming m > 1 so the correct answer is m=3, n = 7
