Evaluate the radical expressions or indicate that the root is not a real number.
3sqrt-4^3
A. -64
B. 4
C. -4
D. not a real number
B?
If you mean 3√((-4)^3)
then
= 2√-64 , which is not a real number
I did do that but i had got it wrong
To evaluate the radical expression 3√-4^3, we first need to simplify the expression inside the radical and then find the cube root.
Step 1: Simplify the expression inside the radical:
-4^3 = -4 * -4 * -4 = -64
Step 2: Take the cube root of the simplified expression:
3√-64 = -4
Therefore, the value of the radical expression 3√-4^3 is -4.
So, the correct answer is C. -4.
