So the answer ends up being a matrix with values 1, 3, 4 ?

HOME> [[1, 9, 16]] .^ 0.5      → [[1, 3, 4]]

This has an advantage by not going thru CAS, which may make sqrt inaccurate.

HOME> M1 := [[0.398, 0.571]]
HOME> M1 .^ 0.5

[[0.630872411824, 0.755645419493]]

HOME> CAS("apply(sqrt, M1)")

[[0.630872411823, 0.755645419492]]
