1.	Multiply the following monomials(i) xy, x2y, xy, x(ii) m, n, mn, m3n, mn3(iii) kl, lm, km, klm
Answer» (i) xy, x²y, xy, x xy × x²y × xy × x = x × y × x × x × y × x × y × x = x × x × x × x × x × y × y × y = 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 = m⁶n⁶ (iii) kl, lm, km, klm kl × lm × km × klm = k × l × l × m × k × m × k × l × m = k × k × k × l × l × l × m × m × m = k³ × l³ × m³ = k³l³ × m³ = k³l³m³

Multiply the following monomials(i) xy, x2y, xy, x(ii) m, n, mn, m3n, mn3(iii) kl, lm, km, klm

Answer»

(i) xy, x²y, xy, x

xy × x²y × xy × x
= x × y × x × x × y × x × y × x
= x × x × x × x × x × y × y × y
= 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
= m⁶n⁶

(iii) kl, lm, km, klm

kl × lm × km × klm

= k × l × l × m × k × m × k × l × m
= k × k × k × l × l × l × m × m × m
= k³ × l³ × m³
= k³l³ × m³
= k³l³m³
