The simplified value of `1998^2-1997^2+1996^2-1995^2+1994^2-1993^2` is (a) 11953 (b) 11958 (c) 11963 (d) 11973

(999)^(2)-(998)^(2)=?1992(b)1995(c)1997 (d) 1998

The value of (2^(2001)+2^(1999))/(2^(2000)-2^(1998)),

2^(1998)-2^(1997)-2^(1996)+2^(1995)=" K."2^(1995)"

(2005)^(2)-(1995)^(2)= ?

If a+b+c=0 , find the value of (a^2)/((a^2-b c))+(b^2)/((b^2-c a))+(c^2)/((c^2-a b)) (a) 0 (b) 1 (c) 2 (d) 4

The simplified value of the expression (a+b-c)^2+2(a+b-c)(a-b+c)+(a-b+c)^2 is

f:R rarr R is given by f(x)=(a^(x))/(a^(x)+sqrt(a)) , x in R , then f((1)/(1997))+f((2)/(1997))+.....+f((1995)/(1997))+f((1996)/(1997))= (A) 997 (B) 998 (C) 1997 (D) 1998

Simplify: a^6 div a^2 (a) a^4 (b) a^6 (c) a^2 (d) a^0
