Question 3
Indices and LogarithmsGiven that a5/6 × a−1/n = 1, solve for n.
- A.−6.00
- B.−1.20
- C.0.83
- D.1.20
Show the answer and explanation
Answer: D (1.20)
Explanation
a^(5/6 − 1/n) = a⁰, so 5/6 = 1/n and n = 6/5 = 1.20.
Given that a5/6 × a−1/n = 1, solve for n.
Answer: D (1.20)
a^(5/6 − 1/n) = a⁰, so 5/6 = 1/n and n = 6/5 = 1.20.
