" If "((a)/(b))+((b)/(a))=2," then find "((a)/(b))^(10)-((b)/(a))^(10)

If (2a+b)/(a+4b)=3, then find the value of (a+b)/(a+2b)*(2)/(7)(b)(5)/(9)(c)(10)/(7)(d)(10)/(9)

If a+b=7 and ab=10, then find a−b.

Find :(5a + 10b) (5a-10b)

If a+b=10, ab=24 then find a^2+b^2

If a : b = 4 : 5 ," find "(5a-b)/(10a+3b) .

If |vec(a)|=2,|vec(b)|=5 and vec(a).vec(b)=10 then find |vec(a)-vec(b)| .

If a^(2)% of b = b^(3)% of c and c^(4) % of a = b % of b, then the relation between a and b is (a) a = b (b) a = b^(2) (c ) a^(9) = b^(10) (d) a = b^(10)

If a^(2) + b^(2) = 10 and ab = 3 , find : (i) a-b
