Can someone ask me some exponential equations where you change to quadratic (2 Viewers)

Here u go

 

[Qeru]

remember it's not

Im also not sure why you are multiplying by two in the final answer? And where does the go?

 

[CurdleRocket26]

Here u go

Is that right bro

Ok just divide it by log 3/2

 

[Qeru]

Is that right bro

I would suggest revising logarithms as a whole.

What did i do wrong

Here u go

I was talking about this one

Not quite, good attempt though. Remember how to convert an expression in exponential form to a logarithm.

i.e, Recall back to this relationship:

is not equivalent to ?

Oh I haven’t learnt this yet

No log xe = log 5

Thats one of the definitions of the log function usually your meant to learn that at the start...

I have only learnt the log laws not the functions

 

[Qeru]

No log xe = log 5

Even then that isnt equivalent... (and you didn't write that in your working)

 

[Qeru]

I have only learnt the log laws not the functions

Ok prove the log laws?

 

[CurdleRocket26]

Wait should i learn the log functions

In that case, I suggest you touch up more on how logarithms work. Trust me, you will need to know them when you learn calculus in Stage 6.

 

[CurdleRocket26]

Wait should i learn the log functions

E to the power of x =5 you have to take log base 10 of both sides then xlog10 e =log 5 then you divide log 5/log 10

 

[Qeru]

^ Try this next. You said you have learnt it.

Oh ye i have just started learning higher level of maths bc I’m only in Y8
