Key Concepts

Exponential Form

Expressing numbers using exponents (e.g., 2³)

Prime Factorization

Breaking down numbers into prime factors

Log-Exponential Relation

log₍b₎(c) = a ⟺ b^a = c

Important Rules

Integers Only

Exponential form applies to positive integers

Prime Factors

Use smallest prime factors first

Base Restrictions

Logarithm base must be positive and ≠ 1

Inverse Operations

Logarithms and exponentials are inverses

Understanding Exponential Form

What is Exponential Form?

Exponential form is a way to express numbers using exponents. For integers, this means breaking the number down into its prime factors and representing repeated factors as powers.

Prime Factorization Process

  1. 1.Start with the smallest prime (2)
  2. 2.Divide repeatedly until no longer divisible
  3. 3.Move to next prime number
  4. 4.Continue until quotient is 1
