okay one more confusion. how does 3^(n+1) divided by 3^(n+2) simplify to just plain old 3???

Question

anonymous · Answer

it doesn't it simplifies to 1/3

anonymous · Answer

oh. so I guess I had it wrong. how would I go about simplifying the expression?

anonymous · Answer

$$3^{n+1}/3^{n+2} = 3^n \times 3^1 \div s^n 3^2 = 1/3$$

anonymous · Answer

remember ur rules of adding and subtracting exponents

anonymous · Answer

3^(n+2) = 3^(n+1+1) = 3^(n+1) * 3

so that why 3^(n+1) divided by 3^(n+2)
= 3^(n+1) / 3^(n+1) * 3
=1/3

anonymous · Answer

so it equals 1/3. NOT just 3?

anonymous · Answer

yes it equals 1/3

anonymous · Answer

yep. i guess that's how it works.
