What this part means
The lower label selects a particular version, component, or indexed member of the quantity. For example, x₀ and xₜ can be values at different positions.
Its job in the formula
A subscript distinguishes a version, component, step, or member of a quantity. It does not automatically mean multiplication.

The passage around this formula
The value of measuring specifically, rather than folding it into a generic active-power number, is that inference energy is what a model and compiler choice can actually move, while sleep and housekeeping power are largely a board-design and component-selection problem. This is also where standardized measurement earns its keep: before MLPerf Tiny, TinyML hardware and software claims were close to impossible to compare, because there was no shared methodology for what to measure or how, and the working group behind it built a suite that reports latency and energy alongside accuracy across four representative workloads — keyword spotting, visual wake words, small-image…

A subscript is a label attached below a symbol. It often selects a time step, component, category, or member of a sequence.
