Assume that x is a variable that has been declared as a double and been given a value. Write an expression to compute the quartic root of x. The quartic root of a number is the square root of its square root.

Step-by-step explanation:

x is a variable which has been declared of type double.

Then square root of x can be expressed as

The quartic root of a number is the square root of its square root.

In other words, quartic root of x can be expressed as

This can be expressed equivalently as
