Given the statement:

The cube of twice a number.

When we say cube, that means raising a number to the third degree or having an exponent of 3. It must be a common term to familiarize it, similar to that of the term squared, where the number is raised to the second degree or having an exponent of 2. Twice a number involves the multiplication operation. This means that, the variable which is represented by x, will be multiplied 2 times.

The numerical statement can be expressed as,

= (2x)^3
