Answer 1

Resposta:

a=3

b=0

c=1/3

d=0

e=3

f=10

Explicação passo-a-passo:

Answer 2

a)

${5}^{x} = {5}^{3}$

$x = 3$

b)

${9}^{x } = {9}^{0}$

$x = 0$

c)

${3}^{4x + 6} = {3}^{3}$

$4x + 6 = 3$

$4x = 3 - 6$

$4x = - 3$

$x = \frac{ 3}{4}$

d)

${15}^{x \times 2 - 4x} = {15}^{0}$

$x \times 2 - 4x = 0$

$2x - 4x = 0$

$- 2x = 0$

$x = 0$

E)

$x = \frac{ {3}^{3} }{4}$

$x = 3.81884$

f)

$10 \frac{1}{2} = 10 { }^{ - x}$

$\frac{1}{ 2} = - x$

$- x = \frac{1}{2}$

$x = \frac{1}{2}$
