1.


5 sqrt (2y) + 3 sqrt (32y) - 2 sqrt (27y^2)


5 sqrt (2y) + 3 sqrt (16*2y) - 2 sqrt (3*9y^2)


5 sqrt (2y) + 3 sqrt (16) sqrt(2y) - 2 sqrt (9y^2) sqrt 3


5 sqrt (2y) + 3 *4 sqrt(2y) - 2 *3y sqrt 3


5 sqrt (2y) + 12 sqrt(2y) - 6y sqrt 3


17 sqrt(2y) - 6y sqrt 3





2.


sqrt (40b^3) / sqrt (10b^2)


sqrt (40b^3 / 10b^2)


sqrt (4b)


sqrt 4 sqrt b


2 sqrt b





3.


sqrt 5 / sqrt 3


(sqrt 5)(sqrt 3) / (sqrt 3)(sqrt 3)


sqrt (15) / sqrt (9)


(sqrt 15) / 3





4.


sqrt 2x * sqrt 50x


sqrt (2x * 50x)


sqrt (100x^2)


10x





5.


1.2w %26gt; -10.8


w %26gt; (-10.8)/1.2


w %26gt; -9
