# datatable.FExpr.__pow__()¶

Raise x to the power y, or in math notation $$x^y$$.

If x or y are multi-column expressions, then they must have the same number of columns, and the ** operator will be applied to each corresponding pair of columns. If either x or y are single-column while the other is multi-column, then the single-column expression will be repeated to the same number of columns as its opponent.

The power operator can only be applied to numeric columns, and the resulting column will have stype float64 in all cases except when both arguments are float32 (in which case the result is also float32).

## Parameters¶

x
,
y
FExpr

The arguments must be either FExprs, or expressions that can be converted into FExprs.

return
FExpr

An expression that evaluates x ** y.
