Step-by-step solution

To solve the expression x9x2 \frac{x^9}{x^2} , we will apply the Power of a Quotient Rule for Exponents. This rule states that aman=amn \frac{a^m}{a^n} = a^{m-n} , where aa is a non-zero number, and mm and nn are integers. In our case, aa is xx, mm is 9, and nn is 2.


Now, apply the formula:

  • The expression can be rewritten as x92 x^{9-2} .
  • Calculate the exponent: 92=7 9 - 2 = 7 .

Substitute back to get the simplified expression: x7 x^7 .


The solution to the question is: x7 x^7
