Is alternate segment theorem in syllabus?

 

[funky brat]

how much did u sleep? hows prep?

I slept at 11ish.
It's good, we'll do well Insha'Allah. :')

Q9? :/

I never know how to solve these

a-b
Put in the values.
a) 7- (-74) => 7+74 => 81
b) -47 - (-71) => -47 +71 = 24

 

[FLRNAB]

Yep C. Part C. that's where I got problems. A and B are easy.

See if we take the factors independently and try to take their square root we will fail will all. I mean we will get decimals
Also n is a integer.

Square root of 2^3 is decimal but 2^4 is 4.
Do this for all factors. You will find which factors are needed.

You seem to have done Q8 :/

make all the prime factors of 168 a perfect squrae
ans 2x3x7=42

 

[FLRNAB]

Does teh same method apply here?

Q8

Yes.

But that way can't we keep extending all the factors to infinity eg. x^55, x^77 etc etc till we get a decimal or if we don't get a integer by 10 there is no chance?

We are not super computers -__-. CIE won't give you questions requiring powers higher than 10.

 

[FLRNAB]

So let me clear this. For a square.

If integer has no indice, then consider the integer.
If it has a square, remove the power and consider it.
If it is cubic, then keep extending it to ^10 and finding it's square root till you get a decimal.

Right?

No you don't want decimal.

If integer has no indice, then try to take it's square/cube root. If you THINK that it contains decimals then increase the power by 1. Rinse and repeat
If it has a square, try to take it's square/cube root. If you THINK that it contains decimals then increase the power by 1. Rinse and repeat
If it is cubic,try to take it's square/cube root. If you THINK that it contains decimals then increase the power by 1. Rinse and repeat

What's square root of 2? 1.14.............
What's square root of 2^2 (4)? 2

I increased the power by 1.

 

[FLRNAB]

Yes and you wrote it all wrong in your post. After paper everyone is like that. Yeah examiner(Imaginary) hello? Yeah I meant that.

hey guys i face difficulty multiplyng decimal nos with whole ones ..for example 0.48*48.. can anyone of u show its wrkng thru paint like how to place 48 under 0.48 pls pls asapppp..i got to leav to get readyy

 

[Dark Destination]

How to find H.C.F and L.C.M? Please.. someone explain it briefly.. using those 2 x 3 x 3 thingies. :/

 

[peacce]

helpppppppppppppp

Write it as 48/100 and then simplify..

 

[peacce]

Write it as 48/100 and then simplify..

ohhh

 

[Dark Destination]

ohhh

24/50=12/25
keep simplifying..and then cut and stuff... thats all you can do.. and use that kids method of multiplying..

Almost 8 and i just woke up

 

[Dark Destination]

Okay, that was a boring paper.

How'd it go for everyone?

 

[muhammadali233]

So 3 marks lost,2 of which could've been avoided
Do tell other answers of questions you got.

how was paper i nailed it *yes*
