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.
-2ab
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.
-5ab + 7ab -9ab + ab -2ab ... Let's simplify that a bit:ab(-5+7-9+1-2) = -8ab
(2a + b)(a + 3b)
7ab-5ab = 2
Oh, what a happy little math problem we have here! To solve 2a x 5b, we simply multiply the numbers together. So, the answer is 10ab. Just like blending colors on our canvas, we're combining terms in a beautiful way. Great job exploring the world of math today!
7ab itself
The LCM is 280a4b2.
Two negatives make a positive so your equation simplifies firstly as 4ab + 3ab and finally as 7ab.
