Ghanmul in Hindi
घनमूल – किसी संख्या को उसी संख्या से तीन बार गुणा करने पर एक गुणनफल प्राप्त होता है, गुणनफल संख्या का घन तथा स्वयं संख्या गुणनफल का घनमूल कहलाती है। घनमूल का चिन्ह ∛ है
उदाहरण –
- 3 × 3 × 3 = 27 अतः 3 का घन = 27 तथा 27 का घनमूल 3 है
- जिन संख्याओं का घनमूल पूर्ण संख्या में प्राप्त होता है, उन्हे पूर्ण घन संख्या कहते है।
घनमूल निकालने की विधि
किसी पूर्ण घन संख्या का घनमूल गुणनखंड द्वारा निकालने की विधि इस प्रकार है। दी गई संख्या का अभाज्य गुणनखंड निकले। अभाज्य गुणनखंडों में समान खण्डों के त्रिक बनाएं। प्रत्येक त्रिक में से एक-एक लेकर सबों को गुणा करें। अन्त में प्राप्त गुणनफल ही अभीष्ट घनमूल होगा। जैसा की नीचे दिए गए चित्र में दर्शाया गया है।

1 से 20 तक के घन
13 = 1 |
113 = 1331 |
23 = 8 |
123 = 1728 |
