Answer:
Step-by-step explanation:
he product of their units digit is 32...
The only two digits that have product 32 are 4 and 8 So their units digits are 4 and 8
...and that of tens digit is 18...
So their tens digits could be 3 and 6 or 2 and 9 The possibilities are: 34 and 68 64 and 38 24 and 98 94 and 28
The product of two 2-digit numbers is 2632...
So we multiply them to find out: 34×68 = 2312 64×38 = 2432 24×98 = 2352 94×28 = 2632 So they are 94 and 28.
