If for two real constants a and b the expression ax³+3x²-8x+b is exactly divisible by (x+2) and (x-2), then 

lf p + m = 6 and p³ + m³ = 72, then the value of pm is: 

x = y = 333 and z = 334, then value of x³ + y³ + z³ – 3xyz is 

If   then what is the value of  

If  then what is the value of  ?

if a³b = abc = 180, a, b, c are positive integers, then the value of c is 

If then

If a-b=10 and ab=-21, then what is the value of a³-b³?
