Answer:

 \green{ \bf{ {x}^{2}  +  \frac{1}{ {x}^{2} }  = 38}}

Step-by-step explanation:

Find :-

 \bf{ {x}^{2}  +  \frac{1}{ {x}^{2} } }

According to the question→

we \: have \\  \\   \implies \:  \bf{ \bigg(x -  \frac{ 1}{x}  \bigg) = 6} \\  \\ we \: know \: that \\  \\  \implies \: \pink{\bf{ { \bigg(x -  \frac{1}{x}  \bigg)}^{2}  =  {x}^{2}  +  \frac{1}{ {x}^{2} }  - 2 \times x \times  \frac{1}{x} } }\\  \\  \implies \:   \bf{{(6)}^{2}  =  {x}^{2}  +  \frac{1}{ {x}^{2} }  - 2} \\  \\  \implies \:  \bf{ {x}^{2}  +  \frac{1}{ {x}^{2} }  = 36 + 2} \\  \\   \red{ \bf{ \implies \:  {x}^{2}  +  \frac{1}{ {x}^{2} }  = 38}}

Hope it helps you
