Morphology
The meaning 'a number raised to the exponent four' is directly and compositionally derived from 'fourth' (indicating the ordinal 4) combined with 'power' (exponent). This is a conventional mathematical compound found across languages, so a B1 learner who knows both constituent senses will readily understand the MWE.
Etymology
The noun fourth power comes from the simple idea that power means 'raising' a number and fourth means doing that four times. So the fourth power is 'a number multiplied by itself four times'.
