`(a-b)(a-b)-(a+b)(a-b)` is equal to

If tan alpha =(b)/(a), a gt b gt 0 and " if " 0 lt alpha lt (pi)/(4), " then " sqrt((a+b)/(a-b))+sqrt((a-b)/(a+b)) is equal to :

If tanx=b/a , then sqrt((a+b)/(a-b))+sqrt((a-b)/(a+b)) is equal to (a) 2sinx//sqrt(sin2x) (b) 2cosx//sqrt(cos2x) (c) 2cosx//sqrt(sin2x) (d) 2sinx//sqrt(cos2x)

In DeltaABC," if " angleC=90^(@)," then " (a+c)/(b)+(b+c)/(a) is equal to :

a(b-c) +b(c - a) +c(a-b) is equal to

If (a^(2)+b^(2))^(3) = (a^(3)+b^(3))^(2) and ab ne 0 then the numerical value of (a)/(b)+ (b)/(a) is equal to-

If A={a,b},B={c,d},C={d,e} , then {(a,c),(a,d),(a,e),(b,c),(b,d),(b,e)} is equal to

If A={a,b},B={c,d},C={d,e} , then {(a,c),(a,d),(a,e),(b,c),(b,d),(b,e)} is equal to

a, b, c are distinct positive real in HP, then the value of the expression, ((b+a)/(b-a))+((b+c)/(b-c)) is equal to

The product (a+b)(a-b)(a^2-a b+b^2)(a^2+a b+b^2) is equal to: (a) a^6+b^6 (b) a^6-b^6 (c) a^3-b^3 (d) a^3+b^3

|{:(a,b,c),(b,c,a),(c,a,b):}| is equal to
