Answer:
a = 3/2
Explanation:
Solve for a over the real numbers:
8 a^3 - 27 = 0
Hint: | Isolate terms with a to the left hand side.
Add 27 to both sides:
8 a^3 = 27
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides by 8:
a^3 = 27/8
Hint: | Elminate the power on the left hand side.
Take cube roots of both sides:
Answer: a = 3/2
