Question 389559: How do I simplify this radical expression? There is an exponent of 3 in the front part of the radical symbol and a -64 on the inside of the radical symbol
Answer by lwsshak3(11628)   (Show Source):
You can put this solution on YOUR website! I will assume the given exponent of 3 in the front part of the radical is the index. In other words the problem is to find the cube root of -64 which is -4
note: roots of negative numbers of odd indices (3,5,7, etc) are negative real numbers
roots of negative numbers of even indices (2,4,6, etc) are not valid real numbers, and the roots are called imaginary
