Question

Como resolve isso pfv​

Answer 1

Resposta:

Explicação passo-a-passo:

1)

a) 2ˣ = 1/2 => 2ˣ = 2⁻¹ => x = -1

S = {-1}

b) 3ˣ = 1/81 => 3ˣ = 81⁻¹ => 3ˣ = (3⁴)⁻¹ => 3ˣ = 3⁻⁴ => x = -4

S = {-4}

c) 10ˣ = 0,00001 => 10ˣ = 10⁻⁵ => x = -5

S = {-5}

d) 2ˣ = √2 => 2ˣ = 2^¹/₂ => x = 1/2

S = {1/2}

e) 4ˣ = 1024 => 4ˣ = 4⁵ => x = 5

S = {5}

f) 5ˣ = 1 => 5ˣ = 5⁰ => x = 0

S = {0}

g) 2ˣ = 4096 => 2ˣ = 2¹² => x = 12

S = {12}
