Question

ecuaciones exponenciales ejercicios resueltos

Answer 1

$2^{x} = 2^{3x-14}$
x = 3x-14
14 = 3x - x
14 = 2x
7 = x

$2^{2x-2} = 4$
$2^{2x-2} = 2^{2}$
2x -2 = 2
2x = 2+2
2x = 4
x = 2

$5^{x+1} = 625$
$5^{x+1} = 5^{4}$
x+1 = 4
x = 4-1
x = 3

Answer 2

respuesta:

. x-1

3 = 81

. x-1 4

3 =3

x-1 =4

x =4+1

x =5

. x

5 =625

. x 4

5 = 5

x = 4

. -1x

3 =9

. -1x 2

3 =3

-1x =2

x =2%1

x = -2
