Find `a^(3) + b^(3) ` if `a + b = 6, ab = 5`

If a - b = 5 and ab = 6, then (a^3-b^3) is equal to: यदि a - b = 5 और ab = 6 है, तो (a^3-b^3) का मान क्या होगा ?

if a : b = 5 : 3 , find (5a + 8b) : (6a - 7b) .

If a + b = 5 and ab = 6, then what is the vlaue of a ^(3) + b ^(3) ?

If a:b = 3:5 and b:c = 6:7, find a:b:c

If a = 2 and b = 3, find the value of (i) a + b (ii) a^(2) + ab (iii) ab - a^(2) (iv) 2a - 3b (v) 5a^(2) - 2ab (vi) a^(3) - b^(3)
