Step-by-step explanation:
Firstly, multiply the base number by itself 2 times. Example: 9² (Nine is the base number, and two is the exponent. The exponent shows how many times we will multiply the base number to itself. So we have to mutilply our base number 9 to itself, 2 times. 9×9=81. Therefore, our final answer is 81. If it has variables or letters (9x²) then simply copy the variable/s. I hope it helps.
