What this part means
A raised number can be a power. When it is a label or bound, it selects a case or the upper limit of a sum; the formula’s structure distinguishes these uses.
Its job in the formula
A raised mark can be a power or an index. Its position and the surrounding notation determine which.

The passage around this formula
It is worth being explicit about what remained unverified in 1961: Landauer’s paper was a theoretical argument grounded in general reasoning about bistable physical systems, not a measurement. No experiment existed, or could have existed with 1961-era instrumentation, capable of resolving a T2 heat signature from a single erased bit — that quantity, at room temperature, is on the order of 10^{-21} joules, far below the noise floor of any calorimetry available at the time. The principle stood as an unconfirmed but increasingly trusted theoretical result for more than fifty years.

An exponent tells how a base is used in multiplication. In x³, x is the base and 3 is the exponent: x³ = x × x × x.
