Answer:

x = 11

Step-by-step explanation:

[tex]x^{2}[/tex] = 121

This means that 'x' × 'x' = 121

To know the value of x, we need to find the root of 121.

[tex]\sqrt{121}[/tex] = 11

If u mutiply 11 x 11 , you get 121.

Thus, x = 11

Answer:

x = 11, -11

use the formula:   [tex]\sf a^2 = b[/tex]  ➳   [tex]\sf a = \sqrt{b}, \ a = -\sqrt{b}[/tex]

[tex]\hookrightarrow \sf x^2=121[/tex]

changing the sides, changes square ( ² ) to square root ( ±√ )

[tex]\hookrightarrow \sf x=\pm \sqrt{121}[/tex]

[tex]\hookrightarrow \sf x=\sqrt{121},\:x=-\sqrt{121}[/tex]

[tex]\hookrightarrow \sf x=11,\:x=-11[/tex]
