III. Multiplication of Monomials.
11.) (x³) (x²)= x5
Sol'n: (x³) (x²)
=3+2
=x512.) (2y⁴) (y)= 2y5
Sol'n: (2y⁴) (y)
= 2y⁴+ 1
=2y513.) (4b) (-3b²)= 12b³
Sol'n: (4b) (-3b²)
= 4(-3) b³
= -12b³14.) (-5a²) (-4b)= 20a²b
Sol'n: (-5a²) (-4b)
=5(-4) (a²b)
=20 a²b15.) (2m²n) (4m²n²)= 8m⁴n²
Sol'n: (2m²n) (4m²n²)
=2(4)m⁴n²
=8m⁴n²IV. Kinds of Set.
