Complete the multiplication: AB.?

I presume that's a pair of 2x2 matrices?  The answer is B.  I hate just giving the answer, but I don't see any reasonable way to discuss matrix multiplication in this format.  Please be sure you understand WHY it's B before you turn it in.

It would be 171 * the sum from i=0 to (k-1) of 256^i.\n\nExample: for k=0, AB = 256^0*171 = 171\nfor k=1, ABAB=(256^1+256^0) * 171 = 43,947\nfor k=2, ABABAB=(256^2+256^1+256^0) * 171 = 11,250,603

a^24b^24\njust multiply the exponents\n\nhope thie helps!!!

it really doesnt matter...\nyou could do a x b then the answer times c\nb x c and then the answer times a\nor c x a and then the answer times c\n\nif you have a calculator just enter it as a x b x c\n\nno matter how you multiply them you will get the same answer

Assuming you mean S=(c-b)/(b-a) rather than c-1-a...\n\nMultiply both sides by (b-a) to get S(b-a)=c-b\nMultiply the S through to get Sb-Sa=c-b\nAdd Sa+b to both sides to get Sb+b=c+Sa\nFactor out b to get b(S+1)=c+Sa\nDivide both sides by (S+1) to get b=(c+Sa)/(S+1)\n\nKeep in mind this only holds true for b not equal to a because then S would have no value.\n\nIs that what you're looking for?

I see your preferred method is ask it here and have someone else figure it out for you...\n\nI think you'll learn more if you try them yourself.\n\nFor the addition and subtraction I would write them as numbers on top of each other and use carrying and borrowing rules:\n\n176\n+43\n-----\n\n.492\n-273\n------\n\nFor the multiplication, you would again put them on top of each other and multiply a digit at a time, then add the results.\n\n136\nx21\n------\n..136\n272\n-------\n\nFor the division, I would suggest long division\n.. _____\n3 ) 429

The same way as you multiply any number! you just have to remember you're in hex. If you can get your mind to work in base 16 then the questions will look a lot simpler...\n\nBut, a slightly long winded but foolproof way would be to convert the numbers you want to multiply into decimal, perform the multiplication, and then convert the answer back into hex.

Duch, there's some confusion over what the problem is.  It could be a/(3+4b) - a/(3+b)  OR  a/3 +4b -a/3 -b\n\nIf the former, then it boils down to -(11ab)/(9 + 15b + 4b²)\n\nIf the later, 3b
