The Power of Powers
When you calculate the area of a square room that's 5m × 5m, you write 5² = 25m². When finding the volume of a cube box that's 3m × 3m × 3m, you write 3³ = 27m³. Powers (indices) are a shorthand for repeated multiplication, while roots help us work backwards - if a square has area 64m², its side length is √64 = 8m.
