Urgent notice

Finally What do you want to Express Mam !!

Could't find anything to solve !!

what is this?????????????????

isse kahte h attempt ka pressure "kya question hai...... lagta hi nahi ki question h....  

for 1.f(x)=x+1,g(x)=x^2+1

so, f(g(x))=f(x^2+1)

=x^2+1+1

=x^2+2

now,f(-2)=(-2)^2+2(substituting x= -2 )

=4+2=6

for2.

2logx + 2log x^2 + 2logx^3+..........+nlogx^n

=2logx + 2.2logx + 2.3logx+.......+n.nlogx(by formula logx^n=nlogx)

=2logx(1+2+3+.....+n) ( taking out 2logx as common)

=2logx.n(n+1)/2  ( 1+2+3+....+n=n(n+1)/2)

=n(n+1)logx

if u r facing problem in maths u can refer maths books of 11th and 12th science group of any of ur science group friends .it will surely help..
