Let us know how to solve this question How to solve 1^3+2^3+3^3+4^3+5^3 to 20^3 formula calculator.

First write the question on the page of the notebook.

How to solve 1^3+2^3+3^3+4^3+5^3 to 20^3 formula calculator

To know the solution of this article, first of all, according to your understanding, we will write this question in such a way.

\displaystyle {{1}^{3}}+{{2}^{3}}+{{3}^{3}}+{{4}^{3}}+{{5}^{3}}+……+{{20}^{3}}

By understanding this question, we come to know that it is going on according to a chain. Therefore, we will solve this question with the help of the following formula.

FORMULA :

\displaystyle \mathop{S}_{n}={{\left( {\frac{{n(n+1)}}{2}} \right)}^{2}}

here ,

n = 20

putting the value of n in this formula-

\displaystyle \mathop{S}_{{20}}={{\left( {\frac{{20(20+1)}}{2}} \right)}^{2}}

\displaystyle \mathop{S}_{{20}}={{\left( {\frac{{20(21)}}{2}} \right)}^{2}}

\displaystyle \mathop{S}_{{20}}={{\left( {\frac{{\cancel{2}\times 10(21)}}{{\cancel{2}}}} \right)}^{2}}

\displaystyle \mathop{S}_{{20}}={{\left( {10(21)} \right)}^{2}}

\displaystyle \mathop{S}_{{20}}={{\left( {210} \right)}^{2}}

\displaystyle \mathop{S}_{{20}}=44100
