Question

) Identify the perfect cubes among the following.
a) 64, b) 27, c) 36, d) 16, e) 8

Answer 1

Answer:

64 = 4³

27 = 3³

36 = 6²

16 = 4²

8 = 2³

so, the cubes are 64,27,8

Answer 2

Step-by-step explanation:

64= 4x4x4

therefore, 64 is a perfect cube.

27 = 3x3x3

therefore, 27 is a perfect cube.

36 = 2x2x3x3

here we can not form,group of three numbers.

therefore, 36 is non - perfect cube.

16 = 2x2x2x2

16 is non - perfect cube.

8= 2x2x2

therefore, 8 is a perfect cube.
