Marcus Cade on Instagram: "A square root is just asking: What number do I multiply by itself to get this number? A perfect square is a number that does come from a whole number times itself. Examples: √9. = 3→ because 3 × 3 = 9 √16 = 4→ because 4 × 4 = 16 √25 = 5→ because 5 × 5 = 25 The square root of a perfect square is just the number that made it. If a number doesn’t come from a clean same number then it’s not a perfect square and the square root gets messy #teachersofinstagram #education #ma
