To simplify ^3√-72, we can rewrite it as the cubic root of -1 times the cubic root of 72. Since the cubic root of -1 is -1, we have:
^3√-72 = -1 * ^3√72
Now, ^3√72 can be simplified as the cubic root of 8 times 9. The cubic root of 8 is 2, so we have:
^3√72 = 2 * ^3√9
Finally, ^3√9 can be simplified as the cubic root of 3 times 3:
^3√9 = 3
Therefore, ^3√-72 simplified is equal to:
-1 * 2 * 3 = -6
