Question

G , ( | ) । ( 4 mathrm{G}_{text {।। }} | ) 0 ( mathrm{K} / mathrm{s} ). ( mathrm{M}: 46 mathrm{AM} )
18) ( left(x^{2}+frac{1}{x^{2}}right)^{2} )
( begin{aligned} & x^{4}+frac{1}{u^{4}}+2 =& 194+2 =& 196 x^{2}+frac{1}{x^{2}}=& sqrt{196} =& 44 end{aligned} )
( left(x+frac{1}{x}right)^{2}=x^{2}+frac{1}{x^{2}}+2 quad ) We hare found that ( u^{2}+frac{1}{u^{2}}=14 )

# 25. If x' +5=194 find the value of x' +
