## 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) 7l^{2}, – 3n^{2}

(iv) 6m, 3n

(v) – 5x^{2}, – 2x^{2}

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) 7l^{2}, -3n

7l^{2} × (- 3n^{2})

= 7 × l^{2} × (-3) × n^{2}

= 7 × (-3) × l^{2} × n^{2}

= – 21l^{2}

(iv) 6m, 3n

6m × 3n

= 6 × n × 3 ×n

= 6 × 3 × n × n

= 18min

(v) – 5x^{2}, – 2x

(- 5x^{2}) × (- 2x)

= (- 5) × x^{2} × (-2) x x

= (-5) × (-2) × x^{2} × x

= 10x^{3}

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, x^{2}y, xy, x

(ii) m, n, mn, m^{3}n, mn^{3}

(iii) kl, lm, km, klm

हल:

(i) xy, x^{2}y, xy, x

xy x x^{2}y × xy × x

= x × y × x × x × x × x × y × x

= x × x × x × x × x × y × у × у

= x^{5} × y^{3}

= x^{5}y^{3}

(ii) m, n, mn, m^{3}n, mn^{3}

m × n × mn × m^{3}n × mn^{3}

= m × n × m × n × m × m × m × n × m × n × n × n

= m × m × m × m × m × m × n × n × n × n × n × n

= m^{6} × n^{6}

= m^{6} n^{6}

(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

=k^{3} × l^{3} x m^{3}

= k^{3}l^{3} × m^{3}

= k^{3}l^{3}m^{3}

प्रश्न 4

यदि मूलधन (P) = 4x^{2} , समय (T) = 5x और दर (R) = 5y हो तो ब्याज \(\frac { PTR }{ 100 }\) में क्या होगा?

हल:
