Question

найдите корень уравнения 4^5+x=64^3x

Answer 1

$4^{x+5} = 64^{3x}$
$4^{x+5} = (4^{3})^{3x}$
$4^{x+5} = 4^{9x}$
$x+5 = 9x$
$x = frac{5}{8} = 0.625$
Ответ: 0.625

Answer 2

$4^{5+x}=64^{3x} \ \ 4^{5+x}=4^{9x} \ \ 5 + x=9x \ \ -8x=-5 \ \ x= frac{5}{8} =0,625$

Answer 3

откуда -8?

Answer 4

х - 9х = -8х
