`(20b^(3)-8b)/(4b)=`

If (4b^(2)+(1)/(b^(2)))=2, then (8b^(3)+(1)/(b^(3)))=? (a) 0 (b) 1 (c) 2 (d) 5

What is (1)/(a-b) -(1)/(a+b) -(2b)/(a^(2)+b^(2))-(4b^(3))/(a^(4)+b^(4)) -(8b^(7))/(a^(8)-b^(8)) equal to ?

(-8b^(2)+4b-8)+(-2b^(2)-5b-1)

If ST and SN are the lengths of subtangents and subnormals respectively to the curve by^2 = (x + 2a)^3. then (ST^2)/(SN) equals (A) 1 (B) (8b)/27 (C) (27b)/8 (D) ((4b)/9)

If ST and SN are the lengths of subtangents and subnormals respectively to the curve by^2 = (x + 2a)^3. then (ST^2)/(SN) equals (A) 1 (B) (8b)/27 (C) (27b)/8 (D) ((4b)/9)

If ST and SN are the lengths of subtangents and subnormals respectively to the curve by^2 = (x + 2a)^3. then (ST^2)/(SN) equals (A) 1 (B) (8b)/27 (C) (27b)/8 (D) ((4b)/9)

Factorise : a+2 b + a^(3) + 8b^(3)

If(3a+2b):(4a+b)=5:4, then find the value of (8a+b)/(8a-b) is :
