No, the expression 9^(1/2) is not equal to -3. The symbol "^" typically represents exponentiation, and in this case, 9^(1/2) denotes the square root of 9. The square root of 9 is a positive value because the square root operation returns the principal (positive) square root by convention. Therefore, 9^(1/2) is equal to 3, not -3.
