найдите корень уравнения 4^(5-х)=16^(2х-6)

Answer 1

4^(5-х)=16^(2х-6)

4^(5-x)=(4^2)^(2x-6)

4^(5-x)=4^2(2x-6)

4^(5-x)=4^(4x-12)

5-x=4x-12

-x-4x=-12-5

-5x=-17

x=17/5

x=3.4

Answer 2

 4^(5-х)=16^(2х-6)
 4^(5-х)=4^2(2х-6)
(5-х)=2(2х-6) 
5-х=4х-12
5х=17
х=17/5

Answer 3

17/5

Answer 4

да конечно
