Solve (1/81)^x*1/243=(1/9)^−3−1 by rewriting each side with a common base.
elena55 [62]

Answer:

x=(243)log_{\frac{1}{81}}[(\frac{1}{81})-1]

Step-by-step explanation:

you have the following formula:

(\frac{1}{81})^{\frac{x}{243}}=(\frac{1}{9})^{-3}-1

To solve this equation you use the following properties:

log_aa^x=x

Thne, by using this propwerty in the equation (1) you obtain for x

log_{(\frac{1}{81})}(\frac{1}{81})^{\frac{x}{243}}=log_{\frac{1}{81}}[(\frac{1}{81})-1]\\\\\frac{x}{243}=log_{\frac{1}{81}}[(\frac{1}{81})-1]\\\\x=(243)log_{\frac{1}{81}}[(\frac{1}{81})-1]

Can you help me here pls? Asap
boyakko [2]

Step-by-step explanation:

% calculations are totally easy, if you remember to always find and the use 1%.

100% = $2.85

1% = 100%/100 = 2.85/100 = 0.0285

the price difference was

2.91 - 2.85 = $0.06

how many % are these $0.06 compared to yesterday's price ?

that is how many times 1% can fit into this number.

0.06 / 0.0285 = 2.105263158...%

so, rounded this is 2.1%
