Question

Is the expression x3•x3•x3 equivalent to x3•3•3? Why or why not? Explain your reasoning.

Answer 1

If the first expression reads x(cube) • x(cube) • x(cube) and x(cube • cube • cube), then the answer is no. They are not equal. 

 x(cube) • x(cube) • x(cube) will be equivalent to x(to the 9th power) while x(cube • cube • cube) will be equivalent to x( to the 27th power).
