Question

write the cubes of 4 natural number which are multiples of 5 and verify that the cube of a natural number which is a multiple of 5 is a multiple of 125​

Answer 1

Step-by-step explanation:

take 5 cube,=125

10 cube,=1000

15 cube,=3375

20 cube,=8000

125 is a multiple of 125.(125^1)

1000 is a multiple of 125.(125^8)

3375 is a multiple of 125.(125^27)

8000 is a multiple of 125.(125^64)

therefore,cube of any multiple of of 5 is a multiple of 125.

Answer 2

Step-by-step explanation:

1st 4 multiple of 5 =5, 10,15,20

Their cubes =125,1000,3375,8000

125 /125=1

1000/125=8

3375/125=27

8000/125=64

hence verified
