What is the value of 9 squared (9^2)?

The expression ( 9^2 ) represents 9 multiplied by itself. This can be calculated as follows:

[ 9 \times 9 = 81 ]

Thus, the value of ( 9^2 ) is indeed 81. Understanding this concept of squaring a number is fundamental in mathematics, as it forms the basis for working with exponents. Recognizing that squaring means multiplying the number by itself is crucial for solving not only this problem but also more complex expressions involving exponents in algebra and geometry.
