Answer 1

just multiply (2)(2)(2).and 128 divide to the answer

Answer 2

My choices are
A) \[16^{3}\sqrt{2}\]
B) \[4^{3}\sqrt{2}\]
C) \[6^{3}\sqrt{2}\]
D) \[8^{3}\sqrt{2}\]

Answer 3

factor 128 and look for perfect cubes
128 = 64*2
64 = 4*4*4 a perfect cube
pull out your 4 and you see your answer now

Answer 4

You answer would be B because;
2*2*2*√128 is 90.50

If you solve B you would see:
4*4*4*√2 is the same as 90.50 :)
