Question

Help please

Answer 1

\[3^{6n}\le1/81\]

Answer 2

1/81 is the same as 3 to the 4th power

Answer 3

3^4=81

Answer 4

Yes I already put that

Answer 5

so the equation is not true 81<=(1/81)

Answer 6

I'm trying to solve the equation. .... not see if it's true.

Answer 7

what is unknown in the equation

Answer 8

Is that 3^(6n) <= 1/81 ?

Answer 9

Less than or equal, but yeah that is what I put ^^

Answer 10

\(3^{6n}\le \dfrac{1}{81} \)

\( 3^{6n}\le 3^{-4} \)

Answer 11

6n < -4

Answer 12

Okay, I got it, thanks.

Answer 13

\[3^{6n}\le1/81\]
\[6nln(3)\le \ln(1/81)\]
\[6n \le \frac{ \ln(1/81) }{ \ln(3) }\]
\[n \le ?\]

Answer 14

Do you see the process ?

Answer 15

looks like you got it the easier way, nice.
