Write the Java expression to find the sum of cube root of x and the absolute value of y.

Math.cbrt(x) + Math.abs(y)

Two Math methods, joined by +. Math.cbrt(x) returns the cube root directly. An equally acceptable form is Math.pow(x, 1.0/3), but note it must be written 1.0/3 and not 1/3 — integer division would make the exponent 0 and the whole expression 1.0. That is a favourite trap. Math.abs(y) returns the magnitude of y, discarding its sign. Both methods return a double, so their sum is a double.
