If x = 8, y = 27, then the value of \(\left({X^{\frac{4}{3}}+y^{\frac{2}{3}}}\right)^{\frac{1}{2}}\)1. 52. 13. 24. 4

Answer» Correct Answer - Option 1 : 5

Given:

x = 8, y = 27

Calculation:

According to the question

\(\left({X^{\frac{4}{3}}+y^{\frac{2}{3}}}\right)^{\frac{1}{2}}\)

⇒ (84/3 + 272/3)1/2

⇒ (23 × 4/3 + 33 × 2/3)1/2

⇒ (24 + 32)1/2

⇒ (16 + 9)1/2

⇒ (25)1/2

⇒ 5

∴ Required value is 5
