Answer 1

a) $\frac{18}{nx^{2} }$

n=3⇒n²=9 $\frac{18}{9} =2$

b)$\frac{12}{n^{2} }$

n=2⇒n²=4 $\frac{12}{4}=3$

c) n=2⇒n³=8 $\frac{24}{8} =3$

d)n=2 ⇒$n^{4}$=16 $\frac{32}{16}=2$

e)$\frac{6}{n+1}$

n+1∈{2,3} ⇒ n∈{1,2}

f) $\frac{8}{n^{2} }$

n=2⇒n²=4

g)$\frac{100}{n^{2} }$ n²=25⇒n=5

n²=25⇒n=5

h) $\frac{17}{n^{2}+1 }$

n²+1=17⇒n²=16⇒n=4
