(b) (2 points) log 3 (81) log 3 1 27 = log 3 (81) âˆ’ log 3 (27) = 4 âˆ’ 3 = âˆ’ 4 3 (c) (2 points) Suppose log k x = 8. Then log k ( x âˆš x ) = 12. This is because log k ( x âˆš x ) = log k ( x 1 . 5 ) = 1 . 5 log k ( x ). 5. (3 points) Suppose that F and G are functions whose inputs and outputs are real numbers, deFned by F ( x ) = x 2 + 14 x and G ( x ) = âˆš x + 49. Compute the value of G ( F ( p )). G ( F ( p )) = G ( p 2 + 14 p ) = r p 2 + 14 p + 49 = r ( p + 7) 2 = p + 7 2...
