Question 11
IndicesIf x = 64 and y = 27, evaluate (x½ − y⅓)/(y − x⅔)
- A.2⅕
- B.1
- C.5/11
- D.11/43
Show the answer and explanation
Answer: C (5/11)
Explanation
x½ = 8, y⅓ = 3 and x⅔ = 16, so (8 − 3)/(27 − 16) = 5/11.
If x = 64 and y = 27, evaluate (x½ − y⅓)/(y − x⅔)
Answer: C (5/11)
x½ = 8, y⅓ = 3 and x⅔ = 16, so (8 − 3)/(27 − 16) = 5/11.
