Hello, l’m very great full the way you teaching, but my problem is that, l don’t have data l want to attend maths & physical sciences, what. can l do where are you located?
God bless class of 2023😭💗💗💗
Can I get a big AMENN
So grateful of you and the lessons that you give us. You have a way of making things easier for better understanding
It is my pleasure. I want to see you do well and live to your potential
Eyyy the matric of 2022 are blessed we get viedeos everyday🥳🥳🍾
Yebooooooo.... Only doing my bit to help.
@@MlungisiNkosi thank you malume 🤲
Sir u didn't show us the value of x and y
👏👏👏 for soldiering with the paperless! It'll definitely get better with time when it comes to editing!
Thank you Tsholo… Loving this comment ❤️
Class of 2024 welcome 🎉
Hi sir
At 12:30, how did we get r=2 from multiplying 32 by 1/5?
Wouldn't 32×1/5 give us 6.4? Therefore making r=6.4?
1/5 is the exponent not a normal franction.
I am also happy that we are having mathematics videos they wll really help us a lot
I'm happy for you too... 😁
Hi sir. Question one says determine the values of x and y,not r😬😬😬
🤣
@@MlungisiNkosi it easy now because we have the first term and our 😁😁
X=21 y=63❤
@@tintswalokhosa how did you do dat

Thank you sooooooo much sir🔥🔥🔥🔥🔥🔥🔥🔥🔥 This was extremely helpful
You’re welcome
thanks a lot sir ;the lessons you give are really helpful and makes things easier
Hello sir, so grateful to you and the lesson you give us, sorry if I may ask does this concept work for As and A level
Of course it does… Maths is Maths is Maths and the principles stay consistent regardless of the syllabus
Sir,at 17:21,where does the ar^3 come from?
It is term 4 of a geometric sequence…
Sorry sir you said it's term 4 but you put the 3 for term 3
Check again, it's term 4
Thank you for this lesson I just have a quick question how is r=3 the answer to question 1?
Sir how did you get 2 on tn
On the second example no:1 wasn't that supposed to be ar to the power 4 cause is 189 is on the 4th term?
yes it is, he skipped that step and went straight ahead to ar to the power of 3 (since 4-1=3)
Excuse me sir ,lapha ku r^5(1/5),, where's the 1/5 coming from?
Please time stamp your comment so that it’s easier to know where to go
Basically its is removing the exponent 5 to find r so u multiple by1/5 or u just put the 5th root on both sides
Sir if I just factorized 2187 to 3 to the power of 7 and just dropped the basses would I still get full marks
Yes

Malume when will you be doing previous papers on this section?
Please look out soon
@@MlungisiNkosi eish we writing math paper 1 today preliminary exams
Sorry sir but what took this video long by the way good to have you back
I'm sorry we were not able to edit in time.
Why are you dividing term 2 by term 7?
In order to cancel the “a” value and be left with one variable “r”
May God bless you !
Hey sir. On the last qxn. We were asked the values of X and y
Hi sir
Y choose log of I may ask
but sir
u did not solve for x and y
how did you get r=2?
T2/T1 = T3/T2
From thw 1st question.. It says our second term is 6..and u said our T2 is 2..u lost me there.. Love ur vids by the way.. Thank u soo much
Did the lesson help?
@@MlungisiNkosi it did.. I watched it over n over and i got it😍...
@@dineograciousbulala8715 Awesome… I’m glad 😀❤️
Good day Sir, how will I know when to use the log?
When the bases cannot be identical
A few hours left.. Revision
Great job sir
Thanks you
X=21 and y= 63
Class'24❤❤
Welome to class of 2024.
You forgot to show us how can we solve for x and y in this one .
✌BRILLIANT TEACHING
The question say determine the values of x and y sir 😢
here i am screaming for x and y value
Hello, l’m very great full the way you teaching, but my problem is that, l don’t have data l want to attend maths & physical sciences, what. can l do where are you located?
I’m in Johannesburg West and I will be making an announcement about live classes I will be hosting soon.
@@MlungisiNkosi My teacher l’m located in Midrand kaalfontein
How I wish you had replied to all comments, I still cant find x and y. Its 2023
I got it, now I can't find a laughing emoji
I do try to respond to most comments. Just not as promptly at times
red heart
Where is it ?
😀😀was experiencing technical problems@@MlungisiNkosi
U didn't solve x n y
