Oh, dude, the Least Common Multiple (LCM) of 36ab and 4b is 36ab. Since 36ab contains both 36 and a, and 4b only has 4 and b, you just take the highest power of each factor. So, yeah, 36ab it is. Easy peasy lemon squeezy.
It is: 3a(1-4b)
What does this mean? The rightmost digit of {eq}n^j{/eq} is the remainder when {eq}n^j{/eq} is divided by {eq}10{/eq}. yep totaly nor random :))
2a + 4b + 8c = 2(a + 2b + 4c) You could also continue by factoring the inside of the parentheses a bit: 2a + 4b + 8c = 2(a + 2b + 4c) = 2(a + 2[b + 2c])
3a2 - 24ab + 48b2 = 3(a - 4b)2.
2a + 4b - 52a + 4b - 52a + 4b - 52a + 4b - 5
If you mean 8b+4b = 56-16b then the value of b works out as 2
8b - 4b = 4b
5b = 21 + 4b 5b - 4b = 21 + 4b - 4b b = 21
4b - 1 = -4 + 4b + 3first, simplify and add together what you can.4b - 1 = -1 + 4b4b = 4bbecause 4b is always equal to 4b, the answer is infinite.
Well if it is worded right then 4xb-1+(-4)+4b=4b-1-4+4b=4b+4b-1-4=8b-5

4b-b
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
-4b+2 = 18 -4b = 18-2 -4b = 16 b = -4
The expression 18 plus 6 plus 4b simplifies to 24 + 4b.
5-4b = 1
