Question

Which expression is equivalent to (st)(6)

Answer 1

S(6) x t(6) would be the expression that is equivalent to (st)(6)

Answer 2

(st)(6)= s(6) * t(6)

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)
