pow, ^, ** doesn't work, and Scheme seems to be too common a word to be able to effectively google it.

The answer is expt and I am typing because StackOverflow doesn't like too short answers.
From R5RS Standard Pocedures:
(expt z1 z2) Returns z1 raised to the power z2. For z1 0 z1z2 = ez2 log z1 0z is 1 if z = 0 and 0 otherwise.
Searching for "scheme reference" turns up this document.
(expt base power) is what you want. So (expt 2 3) expresses 2^3 and yields 8.
