The objective is to determine the smallest positive integer that must be subtracted from 2750 to obtain a perfect cube.
First, list the cubes of integers to find the largest perfect cube smaller than 2750.
Comparing 2750 with the calculated cubes, we see that 2744 is the largest perfect cube less than 2750.
The integer to be subtracted is the difference between 2750 and this target perfect cube (2744).
The calculation is as follows:
$2750 - 2744 = 6$
Therefore, the least positive integer that should be subtracted from 2750 to make the result a perfect cube is 6.
Evaluate \(21^3 + (-2)^3 + (-19)^3\)
Two different positions of the same dice are shown, the six face of which are numbered from 1 to 6. Select the number that will be on the face opposite to the face having the number '3'.
