343/279

Answer 2

Step-by-step explanation:

3) x^2=49/81

x^2=(7/9)^2

x=7/9

x^3=343/729

or

x^3=x^2*x=(49/81)*(7/9)=343/729

10) (p/q)^-2= 1/(p/q)^2=q^2/p^2

[(a/b)^p=a^p/b^p

a^-b= 1/a^b]

q^2/p^2*(121/100)=1

121/100=p^2/q^2

(p/q)^2=121/100 [ example

p/q=11/root over 100 x^2=16

x=rootover16

x=8]

( p/q)^3= (121/100)*11/rootover100

=1331/100rootover100
