Answer:
(st)(6)= s(6) * t(6)
Step-by-step explanation:
Lets discuss some basic expressions
(f+g)(x)= f(x) + g(x)
(f-g)(x)= f(x) - g(x)
(fg)(x) = (f*g)(x)= f(x) * g(x)
(f/g)(x)= f(x)/ g(x)
(fog)(x) = f(g(x))
(gof)(x)= g(f(x))
given expression is
(st)(6)
(st)(x)= s(x) * t(x) we multiply it
(st)(6)= s(6) * t(6)
