Answer 2

Answer:

I'm replying to this like after 1.5 yrs but here ya go:

Step-by-step explanation:

$4 *2^{x} = 8^{2x-3} \\2^{2} *2^{x} =(2^{3} )^{2x-3}\\2^ { x+2} = 2^{3(2x-3)}$

now solve for x by bringing the exponents separately:

$x+2 = 3(2x-3)\\x+2 = 6x - 9\\2+9 = 6x-x\\11 = 5x\\x = \frac{11}{5} (decimalform = 2.2)$

thus x = 11/5 or 2.2

hope it helps even though I'm late
