theorem Th39: :: FINSEQOP:39

for C, D, E being non empty set
for d being Element of D
for f being Function of C,D
for h being Function of D,E
for F being BinOp of D
for H being BinOp of E st ( for d1, d2 being Element of D holds h . (F . (d1,d2)) = H . ((h . d1),(h . d2)) ) holds
h * (F [:] (f,d)) = H [:] ((h * f),(h . d))
