Q66 / 160 · WBJEE 2011 · Mathematics

The approximate value of \(\sqrt[5]{33}\) correct to 4 decimal places is

A
2.0000
B
2.1001
Correct answer
C
2.0125
D
2.0500

Solution

Hints: \(y=x^{1 / 5} \Delta y=\left(\frac{d y}{d x}\right) \Delta x=1 / 80 \times 1\) \(y=2+1 / 80\)

Hence, the correct answer is option: 'C'.
