Hey mate here is your Answer
Step 1
_take fourth root of both sides.
![\sqrt[4]{ {x}^{4} + \frac{1}{ {x}^{4} } } = \sqrt[4]{142}](https://tex.z-dn.net/?f=++%5Csqrt%5B4%5D%7B+%7Bx%7D%5E%7B4%7D++%2B++%5Cfrac%7B1%7D%7B+%7Bx%7D%5E%7B4%7D+%7D+%7D++%3D++%5Csqrt%5B4%5D%7B142%7D+ "\sqrt[4]{ {x}^{4} + \frac{1}{ {x}^{4} } } = \sqrt[4]{142}")
![\sqrt[4]{ {x}^{4} (1 + {x}^{ - 1})} = \sqrt[4]{142}](https://tex.z-dn.net/?f=+%5Csqrt%5B4%5D%7B+%7Bx%7D%5E%7B4%7D+%281+%2B++%7Bx%7D%5E%7B+-+1%7D%29%7D++%3D++%5Csqrt%5B4%5D%7B142%7D+ "\sqrt[4]{ {x}^{4} (1 + {x}^{ - 1})} = \sqrt[4]{142}")
![\sqrt[4]{ {x}^{4} } \times \sqrt[4]{1 + {x}^{ - 1} } = \sqrt[4]{71 \times 2}](https://tex.z-dn.net/?f=+%5Csqrt%5B4%5D%7B+%7Bx%7D%5E%7B4%7D+%7D++%5Ctimes++%5Csqrt%5B4%5D%7B1+%2B++%7Bx%7D%5E%7B+-+1%7D+%7D++%3D++%5Csqrt%5B4%5D%7B71+%5Ctimes+2%7D+ "\sqrt[4]{ {x}^{4} } \times \sqrt[4]{1 + {x}^{ - 1} } = \sqrt[4]{71 \times 2}")
Step 1
_take fourth root of both sides.
