Question

if a²+b²=0 prove that a=0 and b=0​

Answer 1

Step-by-step explanation:

We know a^2 must be positive number or zero

Similarly b^2 must also be positive number or zero

a^2 + b^2 = 0

a^2 = -b^2

We already know a^2 is positive or zero but we

also came to know that a^2 is equal to -1 * b^2

Therefore a^2 must be zero

Also a^2 = -b^2

Therefore b^2 must be zero
