What Is a Power and a Root?

Power (Exponent)

A power (or exponent) tells you how many times a number (the base) is multiplied by itself.

For example:

2³ = 2 × 2 × 2 = 8

Here:

• 2 is the base
• 3 is the exponent (or power)
• 8 is the result

Powers are fundamental in algebra, physics, finance, and computing from exponential growth to compound interest.

Root (Radical)

A root is the inverse of a power.

It tells you what number, when raised to a given power, produces another number.

For example:

√₃8 = 2 (because 2³ = 8)

In general, the nth root of a number x is written as:

√ₙx = x^(1/n)

So, roots “undo” powers, just like subtraction undoes addition or division undoes multiplication.

The Power & Root Relationship

Powers and roots are inverse mathematical operations.

If:

aⁿ = b

then:

√ₙb = a

Or equivalently:

a^(1/n) = √ₙa

This relationship allows you to switch between exponential and radical forms easily.

Example 1: Convert a Power to a Root

Convert 2³ to root form.

Since 2³ = 8,

it means √₃8 = 2.

So:

Power: 2³ = 8

Root form: √₃8 = 2

Example 2: Convert a Root to a Power

Convert √₄81 to power form.

√₄81 = 81^(1/4)

81^(1/4) = 3

So:

Root form: √₄81 = 3

Power form: 3⁴ = 81

Power Formula

The general formula for power is:

aⁿ = a × a × a × ... (n times)

Example:

5³ = 5 × 5 × 5 = 125

If n is a fraction, say ½, then:

a^(½) = √a

Root Formula

The general formula for the nth root is:

√ₙa = a^(1/n)

Example:

√₃27 = 27^(1/3) = 3

Because 3³ = 27.

This formula is the foundation of the Power & Root Converter allowing seamless back-and-forth conversion.

Step-by-Step Example Calculations

Example 1: Power to Root Conversion

Convert 2⁴ to root form.

Step 1: 2⁴ = 16

Step 2: Express as a root: √₄16 = 2

Result: 2⁴ = 16 = √₄16 = 2

Example 2: Root to Power Conversion

Convert √₃8 to power form.

Step 1: √₃8 = 8^(1/3)

Step 2: 8^(1/3) = 2

Result: √₃8 = 8^(1/3) = 2

Example 3: Fractional Exponent

Calculate 16^(½).

16^(½) = √16 = 4

Result: 4

Example 4: Decimal Exponent

Calculate 27^(0.3333).

27^(0.3333) ≈ 3

Result: 3 (approximate cube root of 27)

Example 5: Negative Exponent

Calculate 2⁻³.

2⁻³ = 1 / (2³) = 1/8 = 0.125

Result: 0.125

Types of Roots and Powers

The converter supports all types of powers and roots, including special cases frequently used in mathematics and science.

Powers and Roots of Negative Numbers

Our converter handles real numbers only. For complex (imaginary) results, you can use our Complex Number Calculator.

Fractional Exponents and Root Conversion

Fractional exponents combine powers and roots in one expression:

a^(m/n) = √ₙ(aᵐ) = (√ₙa)ᵐ

Example:

8^(2/3) = √₃(8²) = √₃64 = 4

So, fractional powers express “power inside a root” or “root of a power.”

The Connection Between Powers, Roots, and Exponents

The exponent rules also apply to roots, since roots can be expressed as exponents.

Power Laws:

1. Multiplication Rule:
   aᵐ × aⁿ = aᵐ⁺ⁿ
   Example: 2³ × 2² = 2⁵ = 32
    
2. Division Rule:
   aᵐ ÷ aⁿ = aᵐ⁻ⁿ
   Example: 2⁵ ÷ 2³ = 2² = 4
    
3. Power of a Power:
   (aᵐ)ⁿ = aᵐⁿ
   Example: (3²)³ = 3⁶ = 729
    
4. Power of a Product:
   (ab)ⁿ = aⁿbⁿ
    
5. Root as a Power:
   √ₙa = a^(1/n)

The Power & Root Converter applies all these laws automatically to ensure accurate and simplified results.

Applications of Powers and Roots

Powers and roots are fundamental across multiple fields. Here are a few examples:

1. Mathematics

Used in algebra, geometry, and calculus to simplify expressions and solve equations.

2. Physics and Engineering

Used in formulas for energy, acceleration, and scaling systems (e.g., inverse square law).

3. Finance

Exponential growth, compound interest, and depreciation all use powers and roots:

Formula:

A = P(1 + r/n)^(nt)

Or find rate:

r = n(√ₙ(A/P) - 1)

4. Data Science

Root mean square (RMS) and geometric means use both powers and roots.

5. Biology and Chemistry

Population growth and reaction rates often follow exponential and root-based models.
