Answer:
29 , 73
Step-by-step explanation:
Consider the ways that digits will give products of 27 and 14.
3x9=27, and 2x7=14.
The units digits are 3 and 9, and the tens digits are 2 and 7; but we do not yet know
for sure which way they go in the two numbers.
There are no more than TWO combinations to check.
23x79=1817
29x73=2117
The two two-digit numbers are 29 and 73.
