Explanation:
11100111^2
the last 4 digits of this binary number = 7 in base 10.
The number 11100000 in base 10 = 1*2^5 + 1*2^6 + 1*2^7
= 224 base 10
So 11100111 = 231 base 10.
231^2 = 53361.
Now convert this to base 8:
We divide by 8
8 | 53361
8 | 6670 remainder 1
8 | 833 rem 6
8 | 104 rem 1
8 | 13 rem 0
8 | 1 rem 5
| 0 rem 1
So the answer is 150161
