If you're solving the equation for X then try to solve for it by separating X from 50, how would Erika do that?

yeval76 · Answer

By turning it into a logarithmic function... i think

jhonyy9 · Answer

,,exponential equation" - where is the term with exponent i dont see it anywhere ?

yeval76 · Answer

Im sorry, it is $$50^x$$

jhonyy9 · Answer

ohhhh yes - this is different sure - yes ?

yeval76 · Answer

yes

jhonyy9 · Answer

so and you know how you can start it to solve ?

yeval76 · Answer

No thats why I am asking you... We are supposed to solve $$50^x = 17$$

yeval76 · Answer

But I am not sure how to

jhonyy9 · Answer

opinion please

jhonyy9 · Answer

do you have anything ?

jhonyy9 · Answer

how you have learned it in your schoole ?

yeval76 · Answer

i think that you have to first change each side into a log function but then after that I'm lost as to how to solve it

mathmale · Answer

You have 50^x = 17 and want to solve for x.

What to do?  Take the log or ln of both sides to eliminate the exponential function 50^x.

What is log 50^x?  What is log 17?

yeval76 · Answer

In what I'm thinking, it would end up like this:
$$xlog50 = \log 17$$

jhonyy9 · Answer

without knowladge about so you not can solve it 

ok try to make log in both sides - what you will get so ?

yeval76 · Answer

$$xlog50 = \log 17$$

jhonyy9 · Answer

yes how you have wrote above is right - now just divide both sides with log 50 and will get the value of x - yes ?

yeval76 · Answer

x = log 50 / log 17

jhonyy9 · Answer

no this is not rieght how you have made it - check it newly please

yeval76 · Answer

Oh ok that was my question! Thank you so much, i was very confused... Do you think you could help me with another one? @mathmale

mathmale · Answer

x log 50 = log 17 has log17 on the right side.

divide both sides of this equation by log 50 to obtain x = (log 17) / (log 50).  End.
