📖 Quick review
The content lists perfect squares for integers from 1 to 100. Each entry shows a number and its square in the form “n × n”. It also provides the square roots for those perfect squares, showing that the square root of n² is n. The list continues through larger values such as 20 × 20 = 400 and 30 × 30 = 900, and reaches 100 × 100 = 10000. Along the way, it includes occasional formatting artifacts, but the mathematical pattern stays consistent: the square grows as n² and the square root returns the original n. The result is a structured practice set for matching squares with their roots.
