Find the values of $x$ in each of the following:$ \left(2^{3}\right)^{4}=\left(2^{2}\right)^{x} $
Given:
\( \left(2^{3}\right)^{4}=\left(2^{2}\right)^{x} \)
To do:
We have to find the value of $x$.
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,
$(2^{3})^{4}=(2^{2})^{x}$
$\Rightarrow 2^{3 \times 4}=2^{2 \times x}$
$\Rightarrow 2^{12}=2^{2 x}$
Comparing both sides, we get,
$12=2x$
$\Rightarrow x=\frac{12}{2}$
$\Rightarrow x=6$
The value of $x$ is $6$.
