Solve the following :$ \sqrt[4]{\sqrt[3]{2^1}}$
Given :
The given term is $ \sqrt[4]{\sqrt[3]{2^1}}$
To do :
We have to solve the given term.
Solution :
$ \sqrt[4]{\sqrt[3]{2^1}}$
$2^1 = 2$
So, $ \sqrt[4]{\sqrt[3]{2^1}} = \sqrt[4]{\sqrt[3]{2}}$
We know that,
$\sqrt[n]{a} = a^ \frac{1}{n}$
$\sqrt[3]{2} = 2^ \frac{1}{3}$
$ \sqrt[4]{2^ \frac{1}{3}}$
$ \sqrt[4]{2^ \frac{1}{3}} = (2^ \frac{1}{3}) ^\frac{1}{4} $
We know that, $ (a^ \frac{1}{n}) ^\frac{1}{m} = a^ \frac{1}{n \times m}$
$(2^ \frac{1}{3}) ^\frac{1}{4} = 2^ \frac{1}{3 \times 4}$
$=2^ \frac{1}{12} $
By reframing this, $\sqrt[n]{a} = a^ \frac{1}{n}$
We get , $a^ \frac{1}{n} =\sqrt[n]{a}$
Therefore, $2^ \frac{1}{12} =\sqrt[12]{2}$
The value of $ \sqrt[4]{\sqrt[3]{2^1}}$ is $\sqrt[12]{2}$
