    Everyone on this website is absolutely brilliant. Thanks, but I can settle for 133 trillion.

    Help with an Abstract Binary Math Problem

    I think I'm getting it. So instead of dividing by 10 I need to divide by the factorial of 10? That leaves us with 133 trillion. And yes, you're right, with a square board the puzzles would be the same essentially, so I would consider it over counting because we count each puzzle 4 times as...

    Help with an Abstract Binary Math Problem

    The answer is two. Does that mean I need to divide the answer by 10? If that is the case, you will get 48,395,803,610,547,993,600. Also known as 48 quintillion. Also Also known as 48 billion billion However, 9x9 leaves you with a perfect square. Which means that anyone of those arrangements is...

    Help with an Abstract Binary Math Problem

    Sorry, I think my mind skipped back to when I found out how many combinations there are of lottery tickets. Ehm, from here I believe I may have to abdicate from the position of "someone smart" as so callously put in your signature. Care to pick up my slack?

    Help with an Abstract Binary Math Problem

    81 ways. So, that would be 1/81. Now that 1 of the squares is absolutely, unvariably determined. We essentially have a problem with 80 objects and 1 mine. So would it be... 1/81 * 1/80 * 1/79 ... * 1/71?

    Help with an Abstract Binary Math Problem

    Not off the top of my head, I do not. Which may or may not be kind of embarassing, considering I am on my way to Calculus next school year.

    Help with an Abstract Binary Math Problem

    So I was trying to figure out a straightforward method to calculating the possible number of combinations on a beginner minesweeper game (81 squares, 9x9, 10 mines) I figure that i can attribute this to binary. Because the 9x9 part shouldn't really matter. It is essentially a 81 bit...

    Natural Logs, adding variable exponents.

    Sorry guys. I'm really not used to writing equations in text format. If I wanted to show that the 2x+2 was a variable on paper I would just make it higher and small. ;P

    Expanding Logarithms with Radicals

    That makes a lot more sense... So is it 1/2(log2x) or (log2x)/2(log2x)

    Expanding Logarithms with Radicals

    Homework Statement log2√xHomework Equations The Attempt at a Solution I thought that it might be something like log2x - log2x but that's not right. The book examples don't have any radicals.

    Natural Logs, adding variable exponents.

    Homework Statement e^2x * e^2 Homework Equations The Attempt at a Solution Really, I'm just a little bit confused on how I would go about adding the exponent. None of the examples in the book cover that. Is it simply e^2x+2?

    Matrice Multiplication, can someone check my work?

    Well, linguistic debates aside, I checked in the back of the book in the selected answers, and it seems I got it right. Thanks for the help, but I have another problem so I posted another thread.

    Cramer's Rule and Determinants

    Homework Statement Use Cramer's rule to solve the linear system.Homework Equations (only showing one, I think if one is explained I will figure out the rest) 2x - y = -2 x + 2y = 14 What I'm told I'm supposed to do, is to take the constants accompanying the variables and make a matrix out of...

    Matrice Multiplication, can someone check my work?

    Homework Statement Its a 3x2 multiplying a 2x2. (3 down 2 across, 3x2) I was gone for the day that my teacher explained it to us, and I am not sure how to do it. I tried, but I want to be sure. Homework Equations 5 2 0 -4 _X_ 3 7 1 6 ___ -2 0The Attempt at a Solution The answer I got was...
