Question

Calcule quanto vale log₁₀1000:

Answer 1

Resposta:

log 1000 + log₃81 - log₅625

log1000 = log₁₀1000 = log₁₀10³ = 3.log₁₀10 = 3.1 = 3

log₃81 = log₃3⁴ = 4.log₃3 = 4.1 = 4

log₅625 = log₅5⁴ = 4.log₅5 = 4.1 = 4

log 1000 + log₃81 - log₅625 = 3 + 4 - 4 = 3

Answer 2

Resposta:

$\textsf{Leia abaixo}$

Explicação passo a passo:

$\mathsf{log_{10}\:1000 = x}$

$\mathsf{10^x = 1000}$

$\mathsf{10^x = 10^3}$

$\boxed{\boxed{\mathsf{x = 3}}}$
