If `4a-7b=14` and `9a=7(a+b)` then dtermine the value of `ab`

If 2^a=3 and 9^b=4 then the value of a.b is

If a/b=3/4 then find the value of 7a-4b:3a+b .

If (a)/(b)=(7)/(4) then find the value of (a+b)/(a-b)

If a + b = 10 and 3/7 of ab=9, then the value of a^3+b^3 is: यदि a + b = 10 और 3/7 of ab=9, है, तो a^3+b^3 का मान:

If (3a-2b)=9 and ab=7 then 9a^2+4b^2=

If a-b = 5, ab = 14, find the value of a + b

If A={1,2,3,4,5} and B={1,3,5,7,9} then find the value of (A-B)uu(B-A)

If a:b =5:14 andb: c = 7 : 3, then find a:b:c

If (3a+7b)/(3a-7b)=(4)/(3) then find the value of the ratio (3a^(2)-7b^(2))/(3a^(2)+7b^(2))

If a+b=7 and ab=12, find the value of a^(2)+b^(2)
