Yes, that is correct.   

The symbol for the determinant is a triangle.

Backslash triangle.  

 \(\triangle \)

It is clear you have rebirthed yourself Doggo,  or is that  xXxTenTacion  ?

It appears at least some of your bad habits are continuing.

When you vote people down for no good reason, you are not invisible to all.  I can see what you get up to.

I strongly suggest that you behave better in this regard.

I can see that your new persona is answering some questions, at a glance they appear to be proper answers.

That is commendable.

I strongly suggest that you continue your good behaviours and lose your bad ones.

Why would you want to make a bad impression (again) ?

It is highly likely that I do not understand the question properly.

BUT

If n=1

then x=1

\(1=1^\frac{a*1+b}{c}\\ 1=1^\frac{a+b}{c}\\ \)

If a=1, b=2 and c=3   (they are all relatively prime.)

 Then a+b+c=6

You are not going to get any positive numbers smaller than those.

Almost.

You certainly only have one sock of the right colour in the mix so the 1 is correct.

But it would be put over the total number of REMAINING socks.

You took one out already so there are not 20 socks to choose from.  

the first one can be any colour, what is the chance of the second one being the same?

You have asked dozens of these.  

If you have not just copied and pasted, which I think is your favoured method, then you would have learned something.

I'll start you off

James has $ X

Pens cost $ a

Pencils cost $ b

Now you can forget about the dollar signs, I just think it is easier if you use a money symbol to start with,

Make an equation for  James and then a second equation for the two of them.

Then get back to me.

If you want me to answer more fully than this in the future you need to discuss what you have already tried.

But do this, or do what you can, and if you are still stuck I will happily help more.

How about proofreading your question....

Please let me know if this agrees with any 'correct' answer you may be given.

I like to learn and improve my understanding here as well.

I put 'correct' in quotations because I would want to see the logic behind it before I would necessarily accept an alternate solution as the better or correct one.

HERE is a much better idea.

Go and do your own homework!

Here is why (let O be the centre of the circle)

Consider minor arc AB

Angle ACB= half of angle AOB = 20 degrees 

{When standing on the same arc the angle at the centre will be twice the angle on the circumference.}

Consider minor arc CD

Angle CBD = half of angle COD = 84 degrees

Pink angle at E = 180-84-20 = 76 degrees.
