How do you simplify (7 3sqrt6y)(2y^2 3sqrt(9y^2))

Question

a) (7 3√6y)(2y²3√9y^2)

 

b) (m²√5)(2m√15m) 

 

Thanks!

Answer 1

a)

( 7 * 3√6 ) ( 2 y^2 3 √9Y^2) =

 

(21 √6) ( 2y ^2 * 3 Y ) =

 

126 Y^3 √ 6

 

b)

     (m^2 √5 ) ( 2m √15m ) =

   

       2 m^3 √( 75m) =

 

        2 m^ 3 ( 5 √3m)=

 

         10 m^3 √(3m)
