Answer:

3\sqrt{32}-2\sqrt{50}+4\sqrt{128}-20\sqrt{18}

3\sqrt{32} = 3\sqrt{2*2*2*2*2}  = 3*2*2\sqrt{2} =12\sqrt{2}

2\sqrt{50}=2\sqrt{5*5*2}  =2*5\sqrt{2} =10\sqrt{2}

4\sqrt{128}=4*\sqrt{2*2*2*2*2*2*2}  =4*2*2*2\sqrt{2} =32\sqrt{2}

20\sqrt{18}=20\sqrt{3*3*2}  =20*3\sqrt{2}=60\sqrt{2}

12\sqrt{2}-10\sqrt{2}+32\sqrt{2}-60\sqrt{2}

Taking \sqrt{2} common

\sqrt{2}(12-10+32-60)

\sqrt{2}(-26)

-26\sqrt{2}
