  1. could you tellme a, b numbers, non 0, whole positive numbers only, that solve the folloving, if any? thank you.
    10**50a+b=3ab
    10 power of 50 times a, plus b = 3 times a b

  2. Hi Andres,

    Is this the correct equation?

    10^(50a) + b = 3ab

    You are providing only 1 equation that consists of two variables (a and b). There are many solutions that will satisfy the above equation.

    For example, let’s take a = 1, then

    10^50 + b = 3b
    10^50 = 3b – b
    10^50 = 2b
    b = (10^50) / 2
    b = 5×10^49

    That is one solution, you can continue with a = 2, a = 3, and so on. There are infinitely many pairs of a and b that will satisfy the equation.
