please help solve, it's important
x^y + y^x =17.....1
x + y =5
solve for x and y
================
2^3 + 3^2 = 17 (by observation)
If you sub 5-y for x then iterative methods can be used.
===============
question 2
x^2= sqrt(x^2 + y^2)
find x and y
x = �1, y = 0 by observation
------------------
question 3
3^x - 2^x =65
x =4
There's no algebraic solution.
Use iteration, eg, Newton's method.

but how
