Solve the following equations for $x$:$ 4^{2 x}=\frac{1}{32} $
Given:
\( 4^{2 x}=\frac{1}{32} \)
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,
$4^{2x}=\frac{1}{2^5}$
$(2^2)^{2x}=2^{-5}$
$2^{4x}=2^{-5}$
Comparing the powers on both sides, we get,
$4x=-5$
$x=\frac{-5}{4}$
Therefore, the value of $x$ is $\frac{-5}{4}$.
