    For what Value of X will the following conditions be satisfied?

    Suppose I have the following six equations: x^60 = y1 x^30 = y2 x^20 = y3 x^15 = y4 x^12 = y5 x^10 = y6 What is the largest value of X (where X is greater than one) such that all y's (y1 through y6) are integers and y1 is smaller than one billion? Obviously the answer is somewhere between one...

    When some integral condition for a pseudomeasure is satisfied?

    My problem is as follows. We have a measurable space (X,F) and a set function \mu :F \rightarrow [0,1] satisfying the following conditions: 1. \mu (\emptyset)=0 2. \mu(X)=1 3. if A \subset B then \mu (A) \leq \mu (B). I call \mu a pseudometric. I have some measurable function f:X \rightarrow R...

    find "a" in P(x) to make P(x) satisfied eq x^2+2x2=0

    consider the integral eapression in x P(x)=x^3 + x^2 + ax +1 where a is a rational number at a=? the value of P(x) is a rational number for any x which satisfied the equation x^2 + 2x - 2 = 0, and in this case the value of P(x) is ..... pls help. I don't understand the question and...

    partial differential equation satisfied by u(x,y)

    Let f : R \rightarrow R be differentiable and define u: R^2 \rightarrowR by u(x,y) := e^{x sin y}f(x - y) show that u satisfies the partial differential equation du/dx + du/dy= (sin y + x cos y)u ?
