Assuming that $x, y, z$ are positive real numbers, simplify each of the following:$ \sqrt[5]{243 x^{10} y^{5} z^{10}} $


Given:

\( \sqrt[5]{243 x^{10} y^{5} z^{10}} \)

To do:

We have to simplify the given expression.

Solution:

We know that,

$(a^{m})^{n}=a^{m n}$

$a^{m} \times a^{n}=a^{m+n}$

$a^{m} \div a^{n}=a^{m-n}$

$a^{0}=1$

Therefore,

$\sqrt[5]{243 x^{10} y^{5} z^{10}}=(243 x^{10} \times y^{5} \times z^{10})^{\frac{1}{5}}$

$=(3^{5} x^{10} \times y^{5} \times z^{10})^{\frac{1}{5}}$

$=3^{5 \times \frac{1}{5}} \times x^{10 \times \frac{1}{5}} \times y^{5 \times \frac{1}{5}} \times z^{10 \times \frac{1}{5}}$

$=3 x^{2} y z^{2}$

Hence, $\sqrt[5]{243 x^{10} y^{5} z^{10}}=  3 x^{2} y z^{2}$.
