Let's assume
unit digit is y
tenth digit is x
so, we will get that number as

Product of two digits is

now, we have
number is bigger than product of it's digits by 52
so, we get

now, we can solve for y

now, we know that x and y must be integers
and those numbers must be between 0 and 9
we can use trial and error method
At x=0:


it is not possible because y should be between 1 and 9
At x=1:

It will make it undefined
so, this is not possible
At x=2:


It is not possible
At x=3:



it is not possible
At x=4:



It is not possible
At x=5:


so, it is not possible
At x=6:


It is not possible
At x=7:



so, it is possible
At x=8:



so, it is possible
At x=9:


so, it is not possible
First number is:
x=7 and y=3


Second number is:
x=8 and y=4


so, two numbers are 73 and 84........Answer
