Question

x2+y2 +z2 =0 then it has (a) unique solution (b) No Solution (c) infinite solution (d) can not be determined. ​

Answer 1

Answer:

option (a) Unique solution.

Step-by-step explanation:

Its clear that Square of a number is always non negative, So x^2,y^2,z^2

all are non negative

And if there sum is zero So it's obvious that there individual value is zero

so x^2 = 0 gives x=0

y^2=0 gives us y=0

z^2 =0 gives z=0

so unique solution is (0,0,0)

hope it helps.
