Answer:
By using prime factorization:
1728 = 2×2×2×2×2×2×3×3×3
1728 = 2³×2³×3³
1728 = 2×2×3
1728 = 12
Using prime factorization:
12167 = 23×23
12167 = 23
Using prime factorization:
32768 (make two groups of 3 digits starting from the right most digit of the number )
32 and 768 are two groups now.
First number's one digit is 2. Because 2³=8.
Second number's one digit is 32. Because 3³<32<4³ = 27<32<64
Now we are gonna choose 3 as tens place. So, the number is 32
