1. What is Power Calculation?

Power calculation (a^b) represents the base (a) raised to the exponent (b). It's a fundamental mathematical operation used across science, engineering, and finance.

2. How Does the Calculator Work?

The calculator uses the power function:

Where:

• \( a \) — Base number (any real number)
• \( b \) — Exponent (any real number)

Explanation: The operation multiplies the base by itself exponent times. For example, 2^3 = 2 × 2 × 2 = 8.

3. Importance of Power Calculation

Details: Power calculations are essential for exponential growth models, compound interest calculations, scientific notation, and many physics equations.

4. Using the Calculator

Tips: Enter any real numbers for base and exponent. The calculator handles positive, negative, and fractional exponents.

5. Frequently Asked Questions (FAQ)

Q1: Can I calculate fractional exponents?
A: Yes, the calculator handles all real number exponents. For example, 4^0.5 calculates the square root of 4 (which is 2).

Q2: What about negative exponents?
A: Negative exponents represent reciprocals. For example, 2^-3 = 1/(2^3) = 0.125.

Q3: What's the result of 0^0?
A: This is mathematically undefined, though some systems may return 1 by convention.

Q4: How precise are the calculations?
A: The calculator uses PHP's pow() function which provides floating-point precision.

Q5: Can I calculate very large exponents?
A: Yes, but results may be displayed in scientific notation for very large or very small numbers.
