69.
f(x)=3^(x-2) ..........recall property of exponents a^m/a^n=a^(m-n)
f(x)=3^x/3^2
f(x)=3^x/9
f(x)=(1/9)(3^x)

I did it, take a look above picture

70. it ask you to find option (IF ANY) are same; so, no answer option is same as any of g(x)
in case we have 4^(x+12)=2^(2(x+12))=2^(2x+24), there is still no option for g(x)
71. use rule 4. a^-n=1/a^n...since you have to multiply by 16, you will have 16a^-n=16(1/a^n)
72. same case as 71; so, no answer option is same as any of g(x)
correct
