1. What are Square and Cube Calculations?

The square of a number is the result of multiplying the number by itself, while the cube is the result of multiplying the number by itself twice. These are fundamental operations in mathematics.

2. How Does the Calculator Work?

The calculator uses the following formulas:

Where:

• \( n \) — Any real number
• \( n^2 \) — Square of the number
• \( n^3 \) — Cube of the number

3. Mathematical Importance

Details: Squaring and cubing are fundamental operations in algebra, geometry, physics, and engineering. Squares appear in area calculations, while cubes appear in volume calculations.

4. Using the Calculator

Tips: Enter any number (positive, negative, or decimal) to calculate its square and cube. The calculator handles all real numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the square of a negative number?
A: The square is always positive because a negative times a negative equals a positive.

Q2: What's the cube of a negative number?
A: The cube remains negative because a negative times a negative times a negative equals a negative.

Q3: What's the largest number this calculator can handle?
A: It's limited by PHP's floating-point precision, typically up to about 1.8e308.

Q4: Can I calculate fractional exponents?
A: This calculator only does squares (power of 2) and cubes (power of 3). For other exponents, use a scientific calculator.

Q5: What are some practical applications?
A: Squares are used in area calculations, quadratic equations. Cubes are used in volume calculations, cubic equations, and physics formulas.
