x^ 3 + 15 = 265

Answer 1

To solve this problem you must apply the proccedure shown below:

1. You have the following expression given in the problem above:

2. You must add a 3 to both sides:

3. Now, you to cube root both sides, as following:

Therefore, the answer is: x = -4

Explanation:

Answer 2

x^3 + 15 = 265
subtract 15 from both sides
x^3 = 250

x = cube root of 250 = 6.30 to nearest hundredth
