To rewrite this expression we can use the sum of cubes identity:
. Notice that we can express 8 as a cube:
, so we can rewrite our first term as
. Since our second term does not have a exact cubic root, we must rewrite as
. Now we have
and
, so lets use the sum of cube identity to rewrite our expression:
We can conclude that we can use the sum of cubes identity to rewrite the expression <span>8x^3+243 as </span>
The answer is 3.0 I belive
