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
Contrast that with the muon’s anomalous magnetic moment, = (g-2)/2 , which remains unresolved. The Fermilab Muon g-2 experiment’s most precise measurement to date, released in August 2023, gives = 116{,}592{,}040(54)10^{-11} , a result precise to 0.20 parts per million [ 5 , 6 ] . Combined with the experiment’s earlier data, the measured value differs from one widely used Standard Model theoretical prediction by (25159)10^{-11} , a discrepancy the collaboration itself describes as reaching 4.2 standard deviations [ 6 ] . This is a genuine, still-live tension, and it is also a genuine, still-live disagreement among theorists — not about the experimental…

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.
