Which of the following is equivalent to  $\sqrt{200}$  ?

(HINT:  Factor Tree)

•  $10\sqrt{2}$  

•  $2\sqrt{100}$  

•  $7\sqrt{2}$  

•  $2\sqrt{10}$  

Simplify: 

 $2\sqrt{45}$  
(HINT:  Factor Tree)

•  $3\sqrt{5}$  

•  $6\sqrt{5}$  

•  $2\sqrt{15}$  

•  $10\sqrt{3}$  

Which of the following statements is TRUE about  $\sqrt{98}$  ?

(HINT:  Factor Tree)

•  $\sqrt{98}=7\sqrt{2}$  
  because the prime factorization of  $98$  is  $2\cdot7\cdot7$  

•  $\sqrt{98}=2\sqrt{7}$  
  because the prime factorization of $98$  is  $2\cdot7\cdot7$  
  

•  $\sqrt{98}=14\sqrt{7}$  
  because the prime factorization of $98$  is  $2\cdot2\cdot7$  
  

•  $\sqrt{98}=14$  
  because the prime factorization of  $98$  has a  $2$  and  $7$
