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

IF |a|=8,|b|=3 and |a×b|=12 , then the value of a.b is

If a + 3b = 12 and ab = 9, then the value of (a - 3b) is: यदि a + 3b = 12 और ab = 9 है, तो (a - 3b) का मान है:

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 abs(a)=2, abs(b)=3, abs(c)=4" and "a+b+c=0 then the value of b*c+c*a+a*b is equal to

If a + b + c = 1, ab + bc + ca = 2 and abc = 3, then the value of a^4 +b^4 +c^4 is equal to _____

If 2a + 3b = 8 and ab = 5, then find the value of 4a^2+9b^2 . यदि 2a + 3b = 8 और ab = 5, तो 4a^2+9b^2 का मान ज्ञात कीजिए ।
