Find the sum of the cubes of the first 10 natural numbers without finding the cube of each no.​

Answer»

Answer:

3025

Step-by-step explanation:

The formula for finding the SUM of CUBES of 'n' numbers is

(\frac{n(n +1)}{2} )^{2}

Here n = 10.

Therefore, the sum is

(\frac{10(10 + 1)}{2}) ^{2} =(\frac{10*11}{2}) ^{2} = (5*11)^{2} =55^{2}

55^{2} = 3025
