## anonymous one year ago Is the expression x3•x3•x3 equivalent to x3•3•3? Why or why not? Explain your reasoning.

$x^3\times x^3\times x^3$ equivalent to $(((x^3)^3)^3)$

Help, I know that the second equation would net me with x^27, but the first would only be x^9 correct?

3. anonymous

yup the first would give you x^9

4. anonymous

I thought so, why is that? .-.

5. anonymous

its one of the properties of exponents. If they have the same base which is "x " then you add the exponents. so you get 3+3+3 which is 9.
