Question

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

Answer 1

No, Because the given numbers have different value. Let’s explain it further.
Notice the variable x that is being used. It is considered as the unknown number
=> In the first equation
=> x3 * x3 * x3 – In this equation unknown variable is being multiplied by 3 each first before you can proceed with multiplying all the three x3
For example, let x = 2
=> 2(3) x 2(3) x 2(3)
=> 6 x 6 x 6
=> 216

=> In the second equation
=> x3 * 3 * 3
=> 2(3) x 3 x 3
=> 54
