Can someone ask me some exponential equations where you change to quadratic (3 Viewers)

[CurdleRocket26]

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

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

Look here

Look here

That’s right cmon

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

I can respect it. Year 8 me would have no idea how to do any of these questions. Take baby steps. You're going to struggle with calculus and trigonometry if you can barely factorise, expand, solve and rearrange equations - all of which are basic skills that are taught in algebra.

Yup sure now prove this identity: for a,b positive numbers and also

Ok you just times it when adding logs

 

[A1La5]

Wait bro i do know how to factorise expand and rearrange

I wasn't saying that about you in particular, it's just an example I'm using to illustrate my point.

Yup why?

Oh k but like am i good for a year 8

 

[CurdleRocket26]

Yup why?

Because it relates to the index law (for example) 6^3*6^4 then you add it

@Qeru is this right

I can't give you a qualitative answer, but you've definitely got potential to do well. Just keep at it and let the results speak for themselves.

So it is possible for me to do 4u MATHS

 

[Qeru]

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

i.e, Recall back to this relationship: View attachment 29933

So you have learnt this? Im confused.

If you work hard and develop a good fundamental understanding of maths. Otherwise I wouldn’t recommend it.

Oh yes i have lol

For me in particular , if so what would u recommend

Bro i will work hard. Can you just explain why you wouldnt recommend it. Also r u talking about me or are you saying this as general advice

General advice. You’re only in Year 8 so it’s pretty impressive that you can do these types of questions. You’ve still got a while to go till Year 12 so it’s hard to make any judgement yet.

Ye thx

Because you need a good fundamental understanding of maths to do 4U. 4U and to a degree, even Extension 1 (induction, etc.) will absolutely shit on you if you don't know your basics.
