Thank you for the opportunity to help you with your question!

according to the given condition,

x^5+100=y^3

therefore,

y^3-x^5=100

y=7 and x=3

satisfies the condition,

let us check,

7^3-3^5=343-243

            =100

hence,

X=3   Y=7

Please let me know if you need any clarification. I'm always happy to answer your questions.
