Question

find the value of x from the equation

Answer 1

$

\dfrac{8^{3x}}{2^{10}}=\dfrac{4^{2x}}{16} \\

\dfrac{2^{3(3x)}}{2^{10}}=\dfrac{4^{2x}}{4^2} \\

2^{9x-10}=4^{2x-2} \\

2^{9x-10}=2^{2(2x-2)} \\

2^{9x-10}=2^{4x-4} \\

9x-10=4x-4 \\

5x-6=0 \\

5x=6 \\

\boxed{x=\dfrac{6}{5}}

$

Hope this helps.
