nil1989 Sayswhat are the last 2 digits of the nos 169^31?

for finding the last 2 digits,always try and find out whether the number can be made to end with 1,which makes it very easy thereafter as final digit in this case will always be 1.

In this case 169 if squared will end up with number ending with 1 :

so (169^2)^29 = (...61)^29 [its enough to find out the last 2 digits)

therefore last 2 digits of the above power number = 51 (5 from 6 *9 = 54 )

bro, in the binomial expansion of (2+1)^1024= 2^1024*1^0+2^1023*1^1.....2^0*1^1024 -1

thus the highest term will be 2^1024-1=2^1023..

am i wrong anywhere??

(3^1024-1)can be written as (2+1)^1024-1 which means in the expansion of (2+1)^1024 last term will be 1 nad will be cancelled by -1....ao the whole expansion will be C(1024,0)2^1024+C(1024,1)2^1023+.......C(1024,1)2^1

LAST TERM IS 1024*2=2048 IE 2^11=2^X

HENCE x=11.

it is 12.. break the above into a^2 - b^2 form.. it will reduce like (3^512 +1) (3^512-1) .. at last (3^2-1)(3^2+1) will be left..

Q) If the graph of the function f(x)= (a^x)-1/x^n*((a^x)+1) is symmetric about y-axis then what is the value of n?

ans -1/3

please explain

TIA

Symmetric about Y axis So ,this is an even function.

so use f(x)=f(-x) to find the value of n

both are same bro,10/(3)^1/2((3^1/2)+1) = 10/(3 + rt(3)) :)

kindly share your approach....
