Answer:

So,

approximate solutions are x = 124.32 and x = 117.68

[tex]exact \: \: solutions \: \: are \\ \: \: x \: = \: \: - \sqrt{11} + 121 \: \: \: \\ and \: \: x \: = \sqrt{11} + 121[/tex]

Step-by-step explanation:

13(x-121)²=143

or, (x-121)² = 11

[tex]x - 121 = \sqrt{11} \\ x = \sqrt{11} + 121[/tex]

so, x = 124.32

OR,

[tex]x = - \sqrt{11} + 121[/tex]

so, x =117.68

for exact solutions,

[tex]x = - \sqrt{11} + 121[/tex]

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