Is anyone familiar with factorials? For a homework question, a section of the equation requires "12!", and the correct answer to solve for that is 12! = (12)(11), but I don't understand. Shouldn't it be 12! = (12)(11)(10)(9)(8) etc.?
Shouldn't it be 12! = (12)(11)(10)(9)(8) etc.? Yes. Continue all the way down to x 1.
Unless 12! is divided by 10!. You should submit your question as it is stated in your book or assignment, so that we know exactly what is being asked from the numbers provided.
(12)(11!) = 12! That ia right!!. All they are asking is to multiply: 12 x11! =12 x [11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1] ALL the stuff in brackets is: 11!. And then just multiplied by one more number 12, which is the same as 12! =12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1.And that is it.
