If p, q, n are three positive real numbers and p > q then which of the following is correct.
p(−1n)<q−1n
Given that, p > q
⇒ 1p<1q (using the property of inequality)
[1p]1n<[1q]1n
Since n is positive [1n] is also positive. So the inequality doesn't change when we raise both sides of the inequality with the positive number 1n.
Hence,
p−1n<q−1n
which is given by option (a).
