Question

1.). Find Area
Length = l^2m^3n
Breadth=4lm^2n^4
2.). Multiply
2 1/2p^2q , -4/7pr^2 , 3 1/4q^2r^3 and -7


*_The circled question _*

Answer 1

Answer:

Area = length x breadth

= (l²m³n) (4lm²n⁴)

Identity: (a^x)(a^y) = a^(x+y)

Area = 4(l²)(l¹)*(m³)(m²)*(n¹)(n⁴)

= 4(l³)(m^5)(n^5)

= 4l³(m^5)(n^5) square units.
