Best ResponseYou've already chosen the best response.2f(27)=sqr root (2(27)5) Multiply 2 by the 27 inside the parentheses. f(27)=sqr root (2*275) Multiply 2 by 27 to get 54. f(27)=sqr root (545) Subtract 5 from 54 to get 49. f(27)=sqr root (49) Pull all perfect square roots out from under the radical. In this case, remove the 7 because it is a perfect square. f(27)=7
