Step-by-step explanation:

x = 9 - √4 = 9 - (±2)

9 - (+2) = 7     9 - (-2) = 11

ix)  

x^4 + \frac{1}{x^4}

for x = 7                                         for x = 11

(7) ^4 + \frac{1}{(7)^4}                                     (11) ^4 + \frac{1}{(11)^4}

= 2401                                          = 14641

x)

x^6 + \frac{1}{x^6}

for x = 7                                         for x = 11

(7) ^6+ \frac{1}{(7)^6}                                     (11) ^6 + \frac{1}{(11)^6}

= 117649                                       = 1771561

xi)

x+\frac{14}{x}

for x = 7                                         for x = 11

7+\frac{14}{7}                                             11+\frac{14}{11}

= 9                                                 = 135/11 = 12.3
