Explanation

The best way to tackle this question is to observe it.

The first thought you could have is picking numbers but the question would become long and tedious, even though could be feasible.

You should pick positive integers or positive fractions but the calculation is long.

Knowing, instead, the rule of the exponents the solution is easier.

Quantity A \(x*x^8 = x^9\)
Quantity B \(x^{3*3} = x^9\)
C is the answer
