Represent the following sentence as an algebraic expression, where "a number" is ti letter \( x \). A number raised to the ninth power.

To express "a number raised to the ninth power" using the letter \( x \), you simply write it as \( x^9 \). This represents the variable \( x \) being multiplied by itself a total of nine times. It's a concise way to convey the operation of exponentiation, making it useful for equations involving powers. When working with exponents, remember that the base (in this case \( x \)) can be any number, including fractions or negative numbers, and raising it to a power will change its value based on the exponent rules. Just like a superhero with the power of nine, \( x \) becomes energized and grows exponentially!
