Question

Find the value of the cube root of (-25 * 40) with steps.

A) -10
B) -20
C) -5
D) -15

Answer 1

To find the cube root of -1000, we look for a number which when multiplied by itself three times results in -1000. The number is -10, so the cube root of (-25 * 40) is -10.

Step-by-step explanation:

To calculate the cube root of the product of -25 and 40, we first need to multiply these two numbers together.

• -25 * 40 = -1000

Next, we find the cube root of -1000. The cube root of a number y is a number x such that x3 = y. In this case, we need to find a number which, when multiplied by itself three times, gives -1000.

We can find that:

• (-10) * (-10) * (-10) = -1000

Therefore, the cube root of (-1000) is -10. Thus, the correct answer is A) -10.
