Question

Simplify:
3n+1-3n+2
3n+3 + 3n+4​

Answer 1

Answer:

(3n×3-3n×9)/(3n×27+3n×81)

=3n(3-9)/3n(27+81)

=-6/108

=-1/18

Answer 2

Step-by-step explanation:

3^n+1-3^n+2=3^n+1(1-3)=-2*3^n+1

3^n+3+3^n+4=3^n+3(1+3)=4*3^n+3

3^n+1-3^n+2/3^n+3+3^n+4=-2*3^n+1/4*3^n+3

=-3^(n+1-(n+3))/2=-3^-2/2=-1/9*2=-1/18
