Answer
a $(x2^4)$ machine followed by $\Big(\text{x}\big(\frac{1}{2}^{}\big)^2\Big)$ machine.
So, it produces $2\times2\times2\times2\times\frac{1}{2}\times\frac{1}{2}=4$
Hence, $(x2^2)$ single machine can do the same job as the given hook-up
So, it produces $2\times2\times2\times2\times\frac{1}{2}\times\frac{1}{2}=4$
Hence, $(x2^2)$ single machine can do the same job as the given hook-up
