Exponents and Roots

🔹 What Is It?

• An exponent means multiplying a number by itself.
  
  

• A root means the opposite: asking what number makes another when multiplied by itself.
  
  

🧩 Clue to Remember

Exponents grow numbers. Roots break them down.

🔹 Example

• 3 squared (3 × 3) = 9
  
  

• The square root of 9 = 3
  
  

• 2 to the power of 4 = 16
  
  

• The fourth root of 16 = 2
  
  

💡 Why It Matters

Understanding exponents and roots is key for scientific notation, algebra, and future math.
