You can expand your exponents in the expression.
The * symbol stands for multiplication.
x^2/x^9 = 1*x*x / x*x*x*x*x*x*x*x*x
The variables in red will cancel eachother out as they divide to 1.
1*x*x / x*x*x*x*x*x*x*x*x
After the division, 1 remains in the numerator and x^7 remains in the denominator.
Final answer:
1/ x^7
