Solution

The correct option is E $x = y$ or the relationship cannot be established
Equation I
$x - \sqrt{121} = 0$
$\Rightarrow x = \sqrt{121}$
$\Rightarrow x = \pm 11$
Equation II
$y^{2} - 121 = 0$
$\Rightarrow y^{2} = 121$
$\Rightarrow y = \sqrt{121}$
$\Rightarrow= \pm 11$
$∴ x = y$

I. x−√121=0 II. y2−121=0

The correct option is E x=y or the relationship cannot be establishedEquation I x−√121=0 ⇒x=√121 ⇒x=±11 Equation II y2−121=0 ⇒y2=121 ⇒y=√121 ⇒=±11 ∴x=y

I. $x - \sqrt{121} = 0$
II. $y^{2} - 121 = 0$

The correct option is E $x = y$ or the relationship cannot be established
Equation I
$x - \sqrt{121} = 0$
$\Rightarrow x = \sqrt{121}$
$\Rightarrow x = \pm 11$
Equation II
$y^{2} - 121 = 0$
$\Rightarrow y^{2} = 121$
$\Rightarrow y = \sqrt{121}$
$\Rightarrow= \pm 11$
$∴ x = y$
