Questions & Step-by-Step Solutions

If x^3 - 8 = 0, what is the value of x?
  • Step 1: Start with the equation x^3 - 8 = 0.
  • Step 2: Add 8 to both sides of the equation to isolate x^3. This gives you x^3 = 8.
  • Step 3: To find the value of x, take the cube root of both sides. This means you need to find a number that, when multiplied by itself three times, equals 8.
  • Step 4: The cube root of 8 is 2, because 2 * 2 * 2 = 8.
  • Step 5: Therefore, the value of x is 2.
