Evaluate of the following:
`(10.4)^3`
Advertisements
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.
