Question

)1 ਤੋਂ 1000 ਤੱਕ ਦੀਆਂ ਕੁੱਲ ਕਿੰਨੀਆਂ ਸੰਖਿਆਵਾਂ ਪੂਰਨ ਘਣ ਹਨ? How many numbers are perfect cube from 1 to 1000?1 से 1000 तक कुल कितनी संख्याएं पूर्ण घन है? *​

Answer 1

Answer:

I I hope you this a correct ans

Answer 2

[ Including 1 and 1000 there are only 10 perfect cube,

10^3 = 1000 so, it can't be more then 10 ] ,

But in between 1 to 1000 there are only 8 perfect cube because then we have to exculed 1 and 1000.

Then only 8 perfect cube will be left:-

8, 27, 64, 125, 21

OR

]a=.1 2 3 4 5 6 7 8 9 10^3

1 8 27 64 125 216 343 512 729 1000

How many?

#a

10

The brute force way:

Generate all the integers from 1–1000, take the cube root of each, & store in b

b=.1r3^~1+i.1000

Find all the cube roots in b that have exact integer values, and list the original integer:

b#~-.,1e7< }."1 (2&x:)b

1 2 3 4 5 6 7 8 9 10
