3×3×3×3

3×3×3×3 denotes the product of four factors, each equal to 3. The value is 81, since 3×3×3×3 = (3×3)×(3×3) = 9×9 = 81. This product can also be written as 3^4, the fourth power of 3, and it can be arranged as 27×3 or 9×9, among other factorizations.

Algebraically, 3×3×3×3 equals 3^4. The prime factorization is 3^4, and the divisors are 1, 3, 9, 27, and 81. Because multiplication is commutative and associative, the order of the factors does not affect the product.

In geometric and dimensional contexts, 3×3×3 represents a cube with side length 3, whose volume is 27 cubic units. Extending the idea to four dimensions, 3×3×3×3 can be interpreted as a four-dimensional grid or hypercube with side length 3. In that sense, its hypervolume (the four-dimensional analogue of volume) is 81 in the appropriate units.

Overall, 3×3×3×3 is a straightforward example of exponent notation, equal to 3^4 and to 81, and it serves as a simple illustration of how repeated multiplication combines in higher-dimensional interpretations.
