Here's your answer, folks:

Without substitution, yes, here? No.

The value of the substituted numbers is essential to finding the correct answer in algebra.

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

5 x 3 = 15

15 squared or cubed = 15 x 15 || 15 x 15 x 15

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

In that case, 15 times a number could not possibly be equal to 5 x 3 unless x was actually 1, which we do not know.

Answer:

NO

Explanation:

5*3^x
\\eq15x

because 3 is raised to the x power not multiplied by it, so it is not equal
