4. What are the properties of Cube and Cube Roots according to RS Aggarwal Solutions Class 8 Chapter-4 Cubes and Cube Roots (Ex 4A) Exercise 4?
To solve the exercise questions of this chapter easily, one must learn certain properties of cubes and cube roots. These properties include:
The cube of an even number will always be even and the cube of an odd number will always be odd.
If a number has 0, 1, 4, 5, 6, or 9 at its units-place then, its cube will also have 0, 1, 4, 5, 6, or 9 at its unit place respectively.
If a number has 2 in its units-place then its cube will have 8 in its units-place and vice versa.
If a number has 3 in its units-place then its cube will have 7 in its units-place and vice versa.
You can find the cube of a number using the identity: (a+b)³ = a³ + 3a²b +3ab² + b³
