The first "chain" is (e^4x minus 4), so we must differentiate this chain as part of the chain rule.

The '-4' is not part of the power of e. Somehow your -4 'escalated quickly' into the power.

The second chain is '4x' while differentiating the e^4x in the first chain. We must also differentiate this second chain '4x' as part of the chain rule.

In effect, the chain rule is applied twice in a row here.
