Evaluate the following:
$99^3$.
Given :
The given term is $99^3$.
To do :
We have to evaluate the given term.
Solution :
$99^3$ can be written as $(100 - 1)^3$
We know that, $(a-b)^3 = a^3 - b^3 - 3ab(a-b)$
So, $(100 - 1)^3 = 100^3 - 1^3 - 3(100)(1) (100-1)$
$= 1000000 - 1 - 300(99)$
$= 1000000 - 1 - 29700$
$ = 999999 - 29700$
$ = 970299$
Therefore, the value of $99^3$ is 970299.
