    Proving m+1 is a Perfect Square when m/8 is a Triangular Number

    see: 6!+1 is not a perfect and similarly for all other multiples of 3 . it is found that 3,6,9,12,15.. are not the values that m can take .see by substituting the values in m!+1.but no condition is mentioned in the sum.so u have to prove that this condition has to be imposed on m.and u are...

    Proving m+1 is a Perfect Square when m/8 is a Triangular Number

    I had worked on this question.i thought that m! is perfectly divisible by 8because m!/8 is a trianguar no.for m! to be a multiple of 8 it has to be >or=4.but m cannot be a multiple of 3 .as u had proved m!+1is not a perfect square. in the question no such condition is provided .so how u prove...

    Proving m+1 is a Perfect Square when m/8 is a Triangular Number

    sorry sorry i forgot mention that this how i worked .the question is to prove m!+1 is a perfect square if m is triangular.

    Proving m+1 is a Perfect Square when m/8 is a Triangular Number

    {if n is the sum of the first a natural numbers then it is a triangular number}eg 6=1+2+3 {a is any integer }show that m!+1is a perfect square if and only if m!/8 is a triangular number.m!/8 is a triangular number.so m!=o(mod8) therefore m has to be minimum 4 and not a multiple of 3.

    6 generals propose locking a safe with a number of different locks

    6 generals propose locking a safe with a number of different locks .each general will be given a key to certain of these locks .how many locks and keys are required and how many keys must each general possesses such that the lock will be opened only if 4 generals are present?

    Bohr's Intuition: How He Knew Angular Momentum Without Proof

    there is no proof for the saying that the orbit in which an electron is moving is an integral multiple of angular momentum? how did bohr guess that it is angular momentum ;why didnot he try other angular variables? my question is how he knew angular momentum without any proof.

    Deriving the Value of the Sum in {_\lim {i} \rightarrow 0}

    it can be an integer certainly not (unless it is not mentioned that x is complex).it can be proved .by solving we get x-1\i.further xi + 1\-1. if x is not complex the expression will never be integer . x has to be an complex which is raised to an odd no: (which is quiet easy to understand...

    Solve tan^2a=tanbtanc: Prove and Simplify

    no there is no relation between the angles.the relation given is not going to help much. I think I will be getting a method for that sum.however thank u

    Solve tan^2a=tanbtanc: Prove and Simplify

    sin(a+b)/sin(a+c)=[ sin(2b)/sin(2c)]^(1/2) then prove tan^2a=tanbtanc I have reached till {tan(a)cos(b)+ sin(b)} * {sin(c)cos(c)}^(1/2)= {tan(a)cos(c)+sin(c)}* { sin(b) cos(b)}^(1/2)

    Finding Perfect Squares of n Factored as a^4*b^3*c^7

    a number n when factorised can be written as a^4*b^3*c^7.find number of perfect square which are factors of n.a,b,c are prime >2. I have no idea how to start? please help.

    Can You Solve These Prime Number Proofs?

    first Q is simple if d is even .2^d is 2^2n .even no: are {expressed in this form } ie 4^n if n is prime i.e. n>or=2 4^n is > or = 16. 4^n -1 is never a prime no. { eg 16-1=15} so n cannot be even.thus we can prove by indirect method.

    How to calculate the number of prime factors of 360?

    sorry re question I am sorry my question was wrong .however I wanted to ask how to find the no: of perfect squares in 360 without factorizing. I am sorry for sending the wrong question.
