If `a=b c` and `c=a-b` , then the value of `a` is `b^2-1` (b) `(b^2)/(b-1)` (c) `b/(b-1)` (d) None of these

If a b c=0 , then find the value of {(x^a)^b}^c (a)1 (b) a (c)b (d) c

If a+b=2c, then the value of (a)/(a-c)+(b)/(b-c) is (1)/(2)(b)1(c)2(d)3

If (a)/(b)+(b)/(a)=2, then the value of (a-b) is (a) 1 (b) 2(c)-1 (d) 0

If (a)/(b+c)=(b)/(c+a)=(c)/(a+b)=K, then the value of K is +-(1)/(2)(b)(1)/(2) or -1(c)-1(d)(1)/(2)

If (FIGURE),the values of a and b are 1,2 (b) 2,3quad (c) 1,3 (d) None of these

For positive numbers a, b, c the least value of (a+b+c)((1)/(a)+(1)/(b)+(1)/(c)) is (a)3 (b)9 (c)27/4 (d)None of these

If a+b+c=0 and a^(2)+b^(2)+c^(2)=1, then the value of a^(4)+b^(4)+c^(4) is 1 b.4 c.(1)/(2) d.(1)/(4)
