The fundamental exponent rules include: Product Rule (aᵐ × aⁿ = aᵐ⁺ⁿ), Quotient Rule (aᵐ ÷ aⁿ = aᵐ⁻ⁿ), Power Rule ((aᵐ)ⁿ = aᵐⁿ), Zero Exponent (a⁰ = 1), and Negative Exponent (a⁻ⁿ = 1/aⁿ).
Fractional exponents represent roots. For example, a¹/² means the square root of a, a¹/³ means the cube root of a, and aᵐ/ⁿ means the nth root of a raised to the m power. Our calculator shows the step-by-step conversion between fractional exponents and radical form.
2³ means 2 × 2 × 2 = 8 (2 raised to the 3rd power), while 3² means 3 × 3 = 9 (3 raised to the 2nd power). The base and exponent positions matter significantly in the result. Our calculator explains this distinction clearly.
Negative exponents indicate reciprocals. For example, a⁻ⁿ = 1/aⁿ. So 2⁻³ = 1/2³ = 1/8 = 0.125. Negative exponents don't make the result negative; they create fractions. Our calculator demonstrates this conversion process step-by-step.
Scientific notation expresses numbers as a coefficient between 1 and 10 multiplied by 10 raised to a power. It's used for very large numbers (like 3.00 × 10⁸ m/s for light speed) or very small numbers (like 1.67 × 10⁻²⁷ kg for proton mass). Our calculator handles scientific notation conversions and calculations.
