nah wrong.

2 * 2 * 2 * 5 * 7 * k = 280k

when we find the squre root of 2 * 2, itl be ofcourse a single 2.
the same way under-root ( 2* 2 * 2 * 2) = 2 * 2
and underoot (2 * 2 * 2 * 2 * 2 * 2) = 2 * 2 * 2

so if we have 2 * 2 * 2, u need to multiply it with such a number that the total number of 2's becomes even
like, 2 * 2 * 2 * 2 is a proper square root.

the same way underoot(2 * 2 * 2 * 2 * 2 * 2 * 3 * 3 * 11 * 11) = 2 * 2 * 2 * 3 * 11
got it?

so all u need to do is, make the number of all prime factors 'even'
280k = 2 * 2 * 2 * 5 * 7 * k
280 k = 2 * 2 * 2 * 2 * 5 * 5 * 7 * 7

so k = 2 * 5 * 7

but if we had 1400 instead of 280 in the Question. where prime factors of 1400 are 2 * 2 * 2 * 5 * 5 * 7
we only need to to increase the number of all the prime factors which is divisible by 2 (coz we have to find SQUARE root, and if we had to find cube root, we'll increase the number of prime factors so that 'that' number of each of the prime factors is divisible by 3)
so we will do it this way 1400k = 2 * 2 * 2 * 2 * 5 * 5 * 7 * 7
k = 2*7

got it?

Thanks very much, Litertly got it

So when we have to find k in perfect square, all we need to do is make PrimeFactorization even.......... and numbers we multiply them by ( to make even, are what we multiply to get answer)
In b) we will increase the numbers to get 3 time each.......... like for 882k
So the Prime factorization is : 2 * 5 * 5 * 7 * 7
So let make all prime factors divisible by 3: 2* 2* 2 * 5 * 5* 5* 7 * 7* 7

We have 2*2*5*7=84........ It looked easy but was beast

Thanks amd, see did I got it?

Isnt that my method?

Ohh! Interesting, we have a copyright claimer

Better patent it before its too late
Just kidding!!!
BTW Did you check if the method is correct?

It works, but not quite a GENUINE KEY to get ans.......! Thanks by the way

Function Notationss? Found in Syllabus, not in book? what the hell is this?

Dark Destination, Awesome12?
coz ive never read the syllabus xD

 

[asadalam]

Function Notationss? Found in Syllabus, not in book? what the hell is this?

Its the functions chapter like f(x)=blah blah etc.

 

[Asad.Babur]

Its the functions chapter like f(x)=blah blah etc.

how hard is this blah blah and how long?

 

[***amd***]

how hard is this blah blah and how long?

a piece of cake u'll do it v easily. In Shaa Allah

 

[Asad.Babur]

a piece of cake u'll do it v easily. In Shaa Allah

Everything I ask you, becomes a piece of cake?
Where is the full cake?

I need 5 to 10 questions of all maths chapter... but syllabus wise ...... #mathematics 4024 the hard onez http://papers.xtremepapers.com/CIE/Cambridge International O Level/Mathematics D (Calculator Version) (4024)/4024_y14_sy.pdf ***amd*** Maganius

just start solving the Qs which are posted here in previous pages
