1.  For the first....just  add  the 4  and 6  and append the radical...so we have...

 

10 4√ [ 2x ]  ⇒  first answer

 

 

2.  A little trickier, NSS

 

Ratio  3 : 2     means that there are  3 + 2  = 5 equal parts......and the longer piece is  3 of these parts

 

So......the longer piece  =  

 

(3 /5) √250   =

 

(3/5) √ [ 125 * 2 ]    =

 

(3/5) √ ( 25 * 5 * 2 ]  =

 

(3/5) √ 25 * √5 * √2  =

 

(3/5) * 5  * √10  =

 

3 √ 10  units

 

 

 

cool cool cool
