Answer:
Number 4: Yes, Numbers 5 and 6: See response below, Number 7: 24 meters
Step-by-step explanation:
Number 4: Negative numbers can't have real number square roots, but negative numbers can have real number cube roots. Take the cube root of -8 as an example. The answer would be -2. This also brings me to another point, discussed in the second response.
Number 5: A cube root is different than a square root being that -
1. the final answer of a cube root is always a negative number while that of a square root is always positive.
2. of course square roots area only applicable to positive numbers, rather cube roots, applicable to both negative and positive numbers
<em>And there are plenty more differences..........</em>
Number 6: I am not sure of a number where the square root and cube root are equal, don't give me credit on this question
Number 7: Take the cube root of 13,824 to get the dimensions, which are all equivalent to 24 (24 * 24 * 24 = 13,824)
