can someone help me with this?

After running memory, the output is the following: > memory Maximum possible array: 9678 YB (1.015e+10 bytes) * Memory available for all arrays: 9678 (1.015e+10 bytes) * Memory used by MATLAB: 5705 MB (5.982e+09 bytes) Physical Memory (R.M): 16218 MB (1.701e+10 bytes) * Limited by System Memory (physical + swap file) available. Which of the following arrays require more than the available memory? (Select all that apply.) x=randn(1,1e9) x=ones(1e4); x=zeros(1e5) x=2randn(1,1e9); x=[randn(1,1e9); randn (1,1e9)]
