Question

sendo log 3 = 0,477 e log 5 = 0,699 qual será o valor de log 45?​

Answer 1

log45

log(9 . 5)

log(3².5)

log3² + log5

2log3 + log5

2(0,477) + 0,699

0,954 + 0,699

1,653 ✓

Answer 2

Resposta:

$log(45) = log(9 \times 5)$

$log(9 \times 5) = log(9 ) + log(5) = x$

$2 log(3) + log(5) = x$

$x = 2(0.477) + 0.699$

$x = 1.653$
