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

It's not the same because in the first problem you're cubing x3 and in the second one you're doing something completely different

The expressions are not the same thing, x3•x3•x3 is not equivalent to x3•3•3. They mean different things and when simplified they do not result to the same expression.

x^3•x^3•x^3 = x^(3+3+3) = x^9

x^3•3•3 = x^(9•3) = x^27
