భావన:

ఏదైనా సంఖ్య యొక్క వర్గమూలాన్ని కనుగొనడానికి, దానిని కారకం చేయండి.

లెక్కింపు:

4050 = 2 × 3 × 3 × 3 × 3 × 5 × 5

4050 లో 2 తో గుణిస్తే

4050 × 2 = 8100

ఇప్పుడు, √8100 = √ (2 × 2 × 3 × 3 × 3 × 3 × 5 × 5)

⇒ √8100 = 2 × 3 × 3 × 5 = 90

8100 ను పొందడానికి 4050 ను 2 ద్వారా గుణించండి, వీటిలో వర్గమూలం 90.
