If a, b, c are the sides of a triangle ABC, then \({a^{\frac{1}{p}}} + {b^{\frac{1}{p}}} - {c^{\frac{1}{p}}}\) where p > 1, is

This question was previously asked in
NDA II 2015 GAT Previous Year Paper (16-Dec-2015)
The correct answer is

always positive

Concept:

  • The triangle inequality states that for any triangle, the sum of the lengths of any two sides must be greater than or equal to the length of the remaining side.

Calculation:

Given: a, b, c are the sides of a triangle ABC

Since a, b, c are positive numbers.

⇒ a1/p, b1/p, c1/p are positive numbers.     ...(∵ p > 1)

We know that the sum of any two sides must be greater than the third side.

⇒ a1/p + b1/p > c1/p

⇒ a1/p + b1/p - c1/p > 0

∴ Option 2 is correct.
