((64^(3/4)*(sqrt(2)/2))^(-1/2)*(4sqrt(2))^3*sqrt(2))^(1/3)

I need to solve this, but i simply don't know how to start. So anyone can solve it, and post here every step of it?

Thanks.

((64(34)×(22))(12)×(4×2)3×2)(13)

 

mmm that looks scary doesn't it. :)

 

(64(34×12)×(2(12)21)(12)×43×(2(12))3×2(12))(13)

 

 

(64(38)×(2(121))(12)×43×2(32)×2(12))(13)

 

 

(64(38)×(2(12))(12)×43×2(32+12))(13)

 

 

(64(38)×(2(14))×43×22)(13)

 

 

64(18)×(2(112))×4×2(23)

 

(26)(18)×(2(112))×22×2(23)

 

2(34)×2(112)×22×2(23)

 

2(912)×2(112)×2(2412)×2(812)

 

Now    -9+1+24+8=24

 

2(2412)

 

22=4

By doing it so slowly to show you all the steps it actually made it seem much harder. :)
