Welcome to the guessing game!
I've taken a number between 2 and 10 and raised it to a power between -2 and 2.
Your task is to guess the number and its power.
Here's the result: 8.0
Hint: The number is raised to the power of 1, so it remains unchanged!
Guess the number: Guess the exponent: Congratulations! You guessed correctly.
