Problem#4

directions: Perform the indicated multiplication. Then simplify each radical expression. 

sqrt3 Multiplied by sqrt 5 



Answer:



  sqrt%283%29 * sqrt+%285%29



  sqrt+%283%2A5%29



  sqrt+%2815%29



Problem#28

directions: Perform the indicated multiplication. Then simplify each radical expression. 

sqrt7 (2sqrt3 + 3 sqrt7) 



Answer:

          

    sqrt%287%29+%282%28sqrt%283%29%29+%2B+3%28sqrt%287%29%29%29



    sqrt%287%29%2A+2%28sqrt%283%29%29 + sqrt%287%29%2A+3%28sqrt%287%29%29



    2%28sqrt+%287%2A3%29%29 + 3%28sqrt%287%2A7%29%29



    2%28sqrt%2821%29%29 + 3 * 7



    2%28sqrt%2821%29%29 + 21  





Problem#50

Perform the indicated division. Rationalize the denominator if necessary. Then simplify each radical expression. 

(18+sqrt567)/(9)





Answer:



   %2818%2B+sqrt%28567%29%29%2F%289%29



   %2818+%2B+sqrt+%2881%2A7%29%29%2F9

  

   %2818+%2B+9%28sqrt%287%29%29%29%2F9



   9+%282+%2B+sqrt%287%29%29

   ____________

        9



   %282+%2B+sqrt%287%29%29
