Question

{(3^n+2)-(3^n+1)}/{(3^n+4)+(3^n+1)}
please explain the answer for a 5 star review​

Answer 1

Answer:

Step-by-step explanation:

ust let y=3^n

∴given expression

=(3^n)+(3^1×3^n)/{((3^n)+(3^n/3)}

=(y+3y)/{y+(y/3)}

=(1+3)/(1+(1/3))

=4/{(4/3)}

= 3 ♬ ♬♬

CHECK:【if n=1→(3+9)/(3+1)=12/4=3】

RE-CHECK:【 if n=2→(9+27)/(9+3)=36/12=3】

TRIPLE-CHECK:【if n=0→(1+3)/(1+1/3)=4÷(4/3)=4×(3/4)=3】

EXTRA-CHECK:【if n=3→(27+81)/(27+9)=108/36=3】
