How 7AB in hexadecimal is binary?
Every digit is a power of 16 in hexadecimal, so we have (in decimal): Keep in mind A = 10, B = 11, ... F = 15. 7AB16 = 7 * 162 + 10 * 16 + 11 = 1792 + 160 + 11 = 1963. To convert to binary, we look at powers of 2. Since the largest power of two that can be subtracted from 1963 is 1024, we know that we must go from 210 to 20. Thus we subtract the highest power of 2 that can be subtracted each time. In the brackets is the power of 2 that was subtracted. 1963 - 1024 = 939 (210) 939 - 512 = 427 (29) 427 - 256 = 171 (28) 171 - 128 = 43 (27) 43 - 32 = 11 (25) 11 - 8 = 3 (23) 3 - 2 = 1 (21) 1 - 1 = 0 (20) When you've done this, list all of the powers from 10 to 0 and put a 1 if you did subtract that number. 10 9 8 7 6 5 4 3 2 1 0 Power of 2 ..1 1 1 1 0 1 0 1 0 1 1 Was the number subtracted? (ignore the dots, they're used to pad) Thus the number in binary is 11110101011.
3ab plus 7ab-12ab equals?
-2ab
What is 3a x 4b simplified?
To simplify the expression 3a x 4b, you multiply the coefficients (numbers) together, which gives you 3 x 4 = 12. Then, you multiply the variables together, which gives you a x b = ab. Therefore, the simplified expression is 12ab.
How do you find the sum of -5ab plus 7ab plus -9ab plus ab plus -2ab?
-5ab + 7ab -9ab + ab -2ab ... Let's simplify that a bit:ab(-5+7-9+1-2) = -8ab
What is the answer to 2a squared plus 7ab plus 3b squared?
(2a + b)(a + 3b)
What is 7ab-5ab?
7ab-5ab = 2
2a x 5b?
The expression 2a x 5b represents the product of 2 times a times 5 times b. This simplifies to 10ab, where 10 is the product of 2 and 5, and a and b are variables that are being multiplied together. This expression cannot be further simplified unless the values of a and b are known.
What is the greatest common factor of 7ab?
7ab itself
What is the LCM of 7ab 8a3b2 10a4?
The LCM is 280a4b2.
