Because there is no number that could be multiplied BY ITSELF and still be negative:
-2 x -2 = 4
2 x 2 = 4
But, cubed root works because a negative can be three times and still be negative:
-4 x -4 x -4 = -64
Hope this helps!
Answer:
The best estimate for the given calculation is 2.8.
Step-by-step explanation:
To determine the correct option regarding the result of this calculation, the mathematical resolution of the same must be developed:
-14 x 1 /9 x (-2 x 9/10) = X
-14 x 1 / 9 x (-18 / 10) = X
-14 x 1 / 9 x -1.8 = X
-14 / 9 x -1.8 = X
-1.555555 x -1.8 = X
2.8 = X
Therefore, the best estimate result for this mathematical operation is 2.8.
The answer is D. hope this helped :)
