Advertisements
उत्तर
Let us consider a number n. Its cube would be \[n^3\] .
If the number n is multiplied by 5, it becomes 5n.
Let us now find the cube of 4n, we get:
\[\left( 5n \right)^3 = 5^3 \times n^3 = 125 n^3\]
Therefore, the cube of 5n is 125 times of the cube of n.
Thus, if a number is multiplied by 5, its cube is 125 times of the cube of that number.
