[(a)/(b)+(b)/(a)=-1],[" find "a^(3)-b^(3)=]

If a=2, b= 3 find the values of (a^(b) + b^(a))^(-1) (ii) (a^(a) + b^(b))^(-1)

a+b+c=6and(1)/(a)+(1)/(b)+(1)/(c)=(3)/(2), then find (a)/(b)+(b)/(c)+(b)/(a)+(b)/(c)+(c)/(a)+(c)/(b)

if a=2,b=3 find (a)(a^(b)+b^(a))^(-1)

If the points ((a^(3))/(a-1),(a^(2)-3)/(a-1))((b^(3))/(b-1),(b^(2)-3)/(b-1)),((c^(3))/(c-1),(c^(2)-3)/(c-1)) are a!=1,b!=1,c!=1, then find the value of abc-(ab+bc+ca)+3(a+b+c)

If A=[(1,2),(3,4)], B=[(2,1),(4,3)] , find (A-B)(A+B) and A^2-B^2 .

If a*b=(ab)/(a+b), find the value of 3*(3*-1)*-3(b)-1.5(c)-1(d)(2)/(3)

If a - b = - 1 then find the value of (a^(3)-b^(3)+3ab+1)

If (a)/(b)=(3)/(4) , find the value of the ratio (3a+b)/(3a-b) .
