Ответ:
x ≈ - 2.289
Step-by-step explanation:
Given
- 35 = 3x³ + 1 ( subtract 1 from both sides )
- 36 = 3x³ ( divide both sides by 3 )
- 12 = x³ ( take the cube root of both sides )
= x , thus
x ≈ - 2.289 ( to 3 dec. places )
Ответ:
-2.289
Step-by-step explanation:
1) The first thing we must do is try to get x by itself
3x^3 + 1 = -35
3x^3 = -36
x^3 = -12
2) Now all we have to do is take the cube root of x and -12 to get your answer (this part you'll have to do on a calculator)
x = -2.289...
