Rajasthan Board RBSE Class 8 Maths Chapter 9 बीजीय व्यंजक Ex 9.1
प्रश्न 1
नीचे दिए गए बीजीय व्यंजकों का गुणा करके गुणनफल लिखिए
(i) 3 × 5x
(ii) – 5p, – 2q
(iii) 7l2, – 3n2
(iv) 6m, 3n
(v) – 5x2, – 2x2
हल:
(i) 3 x 5x
= 3 × 5× x
= 15 x
(ii) – 5p, – 2q
(- 5p) × (- 2q)
= (-5) × p × (-2) x q
= (-5) × (-2) × p× q
= 10pq
(iii) 7l2, -3n
7l2 × (- 3n2)
= 7 × l2 × (-3) × n2
= 7 × (-3) × l2 × n2
= – 21l2
(iv) 6m, 3n
6m × 3n
= 6 × n × 3 ×n
= 6 × 3 × n × n
= 18min
(v) – 5x2, – 2x
(- 5x2) × (- 2x)
= (- 5) × x2 × (-2) x x
= (-5) × (-2) × x2 × x
= 10x3
प्रश्न 2
नीचे दी गई गुणन सारणी को गुणा करके पूरा कीजिए
हल:
प्रश्न 3
निम्न एकपदीय व्यंजकों(RBSESolutions.com) को गुणनफल ज्ञात कीजिए
(i) xy, x2y, xy, x
(ii) m, n, mn, m3n, mn3
(iii) kl, lm, km, klm
हल:
(i) xy, x2y, xy, x
xy x x2y × xy × x
= x × y × x × x × x × x × y × x
= x × x × x × x × x × y × у × у
= x5 × y3
= x5y3
(ii) m, n, mn, m3n, mn3
m × n × mn × m3n × mn3
= m × n × m × n × m × m × m × n × m × n × n × n
= m × m × m × m × m × m × n × n × n × n × n × n
= m6 × n6
= m6 n6
(iii) kl, lm, km, klm
kl × Im × km × klm = k × l × l × m × k × m × k × l × m
= k × k × k × l × l × l × m × m × m
=k3 × l3 x m3
= k3l3 × m3
= k3l3m3
प्रश्न 4
यदि मूलधन (P) = 4x2 , समय (T) = 5x और दर (R) = 5y हो तो ब्याज \(\frac { PTR }{ 100 }\) में क्या होगा?
हल:
