Question

3^8*3^5/3^9
И
$2 - 3(2x + 2) = 5 - 4x$
​

Answer 1

1.3^8*3^5/3^9=3^4

2.2 - 3(2x + 2) = 5 - 4x

x=-4,5

Answer 2

$frac{ {3}^{8} times {3}^{5} }{ {3}^{9} } = {3}^{8} times {3}^{5} div {3}^{9} = {3}^{8 + 5 - 9} = {3}^{4} = 81.$

2 - 3 ( 2х + 2 ) = 5 - 4х

2 - 6х - 6 = 5 - 4х

-6х + 4х = 5 - 2 + 6

-2х = 9

х = 9 ÷ (-2)

х = -4,5.

Ответ : х = -4,5.
