Question:

Which of the following is greatest ?

Options:

\(\sqrt {2}\)

\(\sqrt[3]{3}\)

\(\sqrt[4]{4}\)

\(\sqrt[6]{6}\)

Correct Answer:

\(\sqrt[3]{3}\)

Explanation:

(2)\(\frac{1}{2}\)  (3)\(\frac{1}{3}\)  (4)\(\frac{1}{4}\)  (6)\(\frac{1}{6}\)

 Make the power equals to check the biggest value:

a) (26)\(\frac{1}{2\;×\;6}\) = (64)\(\frac{1}{12}\)

b) (34)\(\frac{1}{3\;×\;4}\) = (81)\(\frac{1}{12}\)

c)  (43)\(\frac{1}{4 × 3}\) = (64)\(\frac{1}{12}\)

d) (62)\(\frac{1}{6\;×\;2}\)  = (36)\(\frac{1}{12}\) 

Here,

Option (b) : 3\(\sqrt {3}\) is the biggest value.
