Step-by-step explanation:
Let us consider the numbers are x and y
given that ...
x+y = 9 ==> equation 1
and
x2+y2= 49 ==> equation 2
from eq 1
let y = x-9
substitute y in equation 2
x2 + (x-9)2 =49
By solving we get
x2-9x+20=0
therefore
x=5 and 4
It can satisfy both the situations
4+5=9
(4)2+(5)2=41
Note : Square can't able to represent in the power of a number.So wherever you see the number 2 in right side of any term it represents a square
