2 log₇(x + 8) - log₇(49) = 2

solve itttttttttttttttt

i don't get it

[Thyme]

41

[Nyerp]

41

show me ur proof

[Nyerp]

how the fuck did you do that?!?! are you magic????

[ikanaide]

sorry, I never really understand logarithims either. ~_~

[Nyerp]

u prolly just put it into wolframalpha >:|

[Thyme]

u prolly just put it into wolframalpha >

lol yeah

[Nyerp]

does anyone know how to actually do it

[ME##]

i'm 'doing' it


am i doing it right?  we'll see

[Nyerp]

argh the next question is bullshit and it won't accept my answer

I miss the good old days of pen and paper. The paper would accept your answer no matter what. :'(

[[REDACTED]]

2 log₇(x + 8) - log₇(49) = 2

solve itttttttttttttttt

i don't get it

<=>
log₇(x + 8)² - 2 = 2
<=>
log₇(x + 8)²=4
<=>
(x+8)²=7⁴
<=>
x+8=49
<=>
x=41

[Nyerp]

oh wow i completely ignored the fact that log₇(49) is perfectly solvable

now do this one felty:

log(x + 8) = 1 - log(x - 7)

I miss the good old days of pen and paper. The paper would accept your answer no matter what. :'(

me too

[spoiler]it was actually 4 months ago in high school where i actually learned things >:[[/spoiler]

[?????]

log(x + 8) = 1 - log(x - 7)

10^(x+8)=1-10^(x-7)
solve as normal

[Nyerp]

10^(x+8)=1-10^(x-7)
solve as normal

doesn't work like that bro
