I need help with this HW question please

Quèstion 9
k² + m² = (2a + 1)² + (2b)²
1
= 4a² + 4a +1+4b²
= 4(a² +
a + b²) + 1
= 2(2a? + 2a + 26²) +1
In the above we are proving
the result is irrational
the result is odd
the result is even
the result is rational
A A Moving to the next question prevents changes to this answer.
