(103)3

Answer in Brief
Advertisements

Solution

In the given problem, we have to find the value of numbers

Given `(130)^3`

In order to find  `(130)^3` we are using identity `(a+b)^3 = a^3 + b^3 + 3ab(a+b)`

We can write `(130)^3`as `(100+3)^3`

Hence where   a = 100 ,b = 3

`(130)^3 = (100 + 3)^3`

           ` =(100)^3 + (3)^3 + 3(100)(3)(100+3)`

           ` = 1000000 + 27 + 900 xx 103`

           `= 1000000 + 27 + 92700`

          ` = 1092727`

The value of  `(130)^3` is ` = 1092727`
