what is compliment of 252 give direct answer
Answers
Answer:
We start with the positive version of the number:
|-19| = 19
2. Divide the number repeatedly by 2, keeping track of each remainder, until we get a quotient that is equal to zero:
division = quotient + remainder;
19 ÷ 2 = 9 + 1;
9 ÷ 2 = 4 + 1;
4 ÷ 2 = 2 + 0;
2 ÷ 2 = 1 + 0;
1 ÷ 2 = 0 + 1;
3. Construct the base 2 representation of the positive number, by taking all the remainders starting from the bottom of the list constructed above:
19(10) = 1 0011(2)
4. Determine the signed binary number bit length:
The base 2 number's actual length, in bits: 5.
A signed binary's bit length must be equal to a power of 2, as of:
21 = 2; 22 = 4; 23 = 8; 24 = 16; 25 = 32; 26 = 64; ...
First bit (the leftmost) indicates the sign,
1 = negative, 0 = positive.
The least number that is a power of 2 and is larger than the actual length so that the first bit (leftmost) could be zero is: 8.
[ first of all, we need to bring the prime factors of 252 by prime factorisation method ]
Prime factors of 252
= 2×2×3×3×7
[ as, 7 is not in pair like "2×2" & "3×3" ]
So, smallest number to be multiplied
= 7
[ multiply 7 to the digits ]
252*7=2*2*3*3*7*7
1764=√2*2*3*3*7*7
=2*3*7
=42
Perfect sq. = 1764
Sq. root of perfect sq. = 42
