Observe the digits in the first number and its corresponding number. $328 : 34512$ Here we observe that first digit is $3$ i.e. $3^1$ , next digit is $4$ i.e. $2^2$ and last three digits are $512$ i.e. $8^3$ .

Similarly, we can write for second number $678$ and we get $6^1 7^2 9^3 = 649729 \cdots\cdots(1)$

NOTE : We are not doing multiplication of $6^1 7^2 9^3$ in step $(1)$ . We are just catenating them.
