Question

the least positive number which is subtracted from 1368 to make it a perfect cube​

Answer 1

Answer:

37 is the least positive number which is subtracted from 1368 to make it a perfect cube​

Step-by-step explanation:

To find least positive number which need to be  subtracted from 1368 to make it a perfect cube​ , first we need to find nearest cube

as we can see 1000 = 10³  which is close to 1386 but let check next number cube

11³ = 1331  which is also less than 1368 so 10³ is omitted

now check next number cube also

12³ = 1728  which is greater than 1368

so we can conclude that 1331 is nearest cube less than 1368

Let we have to reduce x from 1368 to get 1331

then

1368 - x = 1331

=> x = 37

37 is the least positive number which is subtracted from 1368 to make it a perfect cube​
