Step-by-step solution

2 steps
  1. Rewrite the given equation using fractional exponents.

    The given equation is (5)x−(23)y=17(\sqrt{5})^x - (\sqrt[3]{2})^y = 17.
    We can express the roots as fractional exponents: 5=51/2\sqrt{5} = 5^{1/2} and 23=21/3\sqrt[3]{2} = 2^{1/3}.
    Substituting these into the equation, we get:

    (51/2)x−(21/3)y=17(5^{1/2})^x - (2^{1/3})^y = 17

    Using the exponent rule (ab)c=abc(a^b)^c = a^{bc}:

    5x/2−2y/3=175^{x/2} - 2^{y/3} = 17
  2. Determine the form of xx and yy for integer powers.

    Since x,y∈Nx, y \in \mathbb{N} (natural numbers), for 5x/25^{x/2} and 2y/32^{y/3} to result in integer values (which is necessary for their difference to be the integer
