13*(a+b)^(3)-a-b

If a:b=2:5, then (3a+2b)/(4a+b)=(16)/(13)( b) (13)/(16)(25)/(22)(d)(20)/(21)

If the 7th and 8th term of the binomial expansion (2a - 3b)^(n) are equal, then (2a +3b)/(2a-3b) is equal to a) (13-n)/-(n+1) b) (n+1)/(13-n) c) (6-n)/(13-n) d) (n-1)/(13-n)

Find the numerically greatest term (s) in the expansion of (4a-6b)^(13)" when "a=3,b=5

If a : b=2:5, then (3a+2b)/(4a+b)= (a) (16)/(13) (b) (13)/(16) (c) (25)/(22) (d) (20)/(21)

Find a and b when (a-2b,13)=(7,2a-3b).
