Answer:
162
Step-by-step explanation:
x=9 which means you grab the 9 and plug it into the x of x to the power of 2 and x to the power of 1 after you do that you multiply it by the power it gives you. So now you have 9 to the power of 2 and that's 18 and 9 to the power of 1 is 9. Then you multiply 18•9 and you get 162.
