Evaluate of the following: 

`(10.4)^3`

थोडक्यात उत्तर

उत्तर

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

Given`(10.4)^3`

In order to find  `(10.4)^3` we are using identity  `(a+b^3) = a^3 +b^3 + 3ab(a+b)`

We can write `(10.4)^3` as  `(10+0.4)^3`

Hence where `a=10,b = 0.4`

 `(10.4)^3 = (10 +0.4)^3`

 `= (10)^3 + (0.4)^3 + 3 (10) (0.4)(10+0.4)` 

`= 1000 + 0 .064+ 12 xx 10.4`

`= 1000 + 0 .064 + 124.8`

`= 1000 +124.864`

` = 1124.864`

The value of `(10.4)^3` is 1124.864.
