How can you write the expression with a rationalized denominator?
3sqrt 2/3 sqrt 6
A) 3sqrt9/3***
B) 2+3sqrt9/6
C) 3sqrt9/6
D) 3sqrt72/3

Let f(x)=x^2+7 and g(x)=x+3/x. find (g*f)(-5)
A) 35/12
B) 35/32
C) 32/35
D) 11/25***

Please correct me if I’m wrong

  1. 3√2 / 3√6
    = √2 / √6 * √6/√6
    = √12/6
    = 2√3/6
    = √3 / 3
    which does not match any of the given choices, check your typing

    f(x)=x^2+7 and g(x)=x+3/x
    (f*g)(x) = (x^2 + 7)*(x + 3/x) , where * is the standard symbol for multiplication.
    (f*g)(-5) = (25+7)(-5+3/-5)
    = 32(-28/5) = -896/5

    again, not one of the given choices.
