Question

zapisz w postaci jednego logarytmu:

2+log3(5)

log 2+3

1-log3

1-ln 5

Answer 1

2 + log 2 ( 5) = log 2 (4) + log 2 (5) = log 2 (4*5) = log 2 ( 20)

2 + log 3 (5) = log 3 ( 9) + log 3 (5) = log 3 (9*5) = log 3 ( 45 )

log 2 + 3 = log 2 + log 1000 = log 2000

1 - log 3 = log 10 - log 3 = log ( 10/3)

1 - ln 5 = ln e - ln 5 = ln ( e/5 )

gdzie

e - podstawa logarytmu naturalnego
