Find the cubic root of -64. (1 point)
Responses
The cubic root of -64 is -4.
To find the cubic root of -64, you can use the formula:
Cubic root of a negative number = - (absolute value of the number) raised to the power of (1 divided by 3).
In this case, the cubic root of -64 is:
(-64)^(1/3)
Taking the absolute value of -64 gives us 64, so we have:
Cubic root of -64 = - (absolute value of -64)^(1/3)
= - 64^(1/3)
Calculating the value of 64^(1/3), we get:
64^(1/3) = ∛64 = 4
So, the cubic root of -64 is:
- 4.
To find the cubic root of -64, you can use the formula:
cubic root of a = ∛a
In this case, a is -64.
So, the cubic root of -64 is ∛(-64).
To calculate this, you can use a calculator or mathematical software that can handle complex numbers.
The cubic root of -64 is -4, because (-4) x (-4) x (-4) = -64.
Therefore, the cubic root of -64 is -4.
