Detailed Solution

Concept- The values are 2 and 3 respectively. Writing any number as the product of its many factors—typically prime factors—is a procedure known as factorisation.
To determine factors of the given number 1125, We utilize the factorization method in this instance.
Then, we multiply this number by each of its factors to write it down. We combine all the powers with the same base together because they can all be added when the basis is the same.
We use a×a=a2  here.
and a3 an an a
1125's prime factorization
Additionally, prime numbers are those that can only be divided by one.
with the actual number.
Since 1125=3m×5n
Write 1125 as the product of its prime factors, or factories.
1125=3×3×5×5×5 
A tree diagram of a given number's factors can be created.
Since number of times 3 is multiplied to itself is 2
 so, we write 3×3=32
And number of times 5 is multiplied to itself is 3
 so, we write 5×5×5=53
Write the product obtained in exponent form.
1125=53×32
Compare the obtained relation with the given 1125=3m×5n
3m×5n=53×32
When the base is the same, we can equate the powers having the same base.
It can be observed that m=2 and n=3
Hence, the correct answer  is m=2 and n=3.
