Let a and b be real numbers such that a + b = 4 and a^4 + b^4 = 16. (a) Find all possible values of ab (b) Find all possible values of a + b (c) Find all possible values of a and b
Hello! Please respond to this text so i know you are here!
I think the only possible way for a and b is 4,0 or 0,4
a) 0
b) 4
c)a=4 or 0 b = 0 or 4
