Recall that $2^{10} = 1,024$. For $10$ cycles: $2^{10} = 1024$. Multiply by initial $100 \implies 102,400$.
Using the PCR exponential amplification equation $N = N_0 \times 2^n$: Substitute $N_0 = 100$ and $n = 10$: $$N = 100 \times 2^{10} = 100 \times 1024 = 102,400.$$ Each thermal cycle doubles the template quantity....
