1) =3^(-7+2)/3^(-9)=3^(-5)/3^(-9)=3^(-5-(-9))=3^4=81

2)=2^(-5+9)/2^(-4)=2^(4)/2^(-4)=2^(4-(-4))=2^(8)=256

3)=7^(-3+9)/7^(4)=7^(6)/7^(4)=7^(6-4)=7^2=49

4)4^8=(2^2)^8=2^(2*8)=2^(16)
2^(16)/2^(13)=2^(16-13)=2^(3)=8

5)8^9=(2^(3))^9=2^(3*9)=2^(27)
64^(3)=(2^(6))^(3)=2^(6*3)=2^(18)

2^(27)/2^(18)=2^(27-18)=2^(9)=512
