यदि `x^(2)+y^(2)+2x+1=0` है तो `x^(31)+y^(35)` का मान क्या होगा?A. -1B. 0C. 1D. 2

Answer» Correct Answer - A
`x^(2)+y^(2)+2x+1=0`
`implies x^(2)+2x+1+y^(2)=0`
`(x+1)^(2)+y^(2)=0`
Hence both terms are squares and there addition is zero so, it can be possible only when both terms are zeros.
`:. x+1=0`
`impliesx=-1`
`y=0`
`:. x^(31)+y^(35)`
=`(-1)^(31)+(0)^(35)=-1`
