Question

(1/3)^x=1/9 solve the equation for x. Round to the nearest two decimal places

Answer 1

x=2

Answer 2

\[3^{-x} = 3^{-2}\]

-x = -2

x = 2

Answer 3

ok thanks to both of you can you tell me if im correct when I say e^x=4 and x=1.39

Answer 4

take logarithm to the base e, and check your log book for Log 4 base e..

Answer 5

(1/3)^x = (1/9)
Solution: => ln(1/3)^x = ln(1/9) {multiply both sides by natural log ln}
=> x*ln(1/3) = ln(1/9) {exponent rule for log/ln}
=> x = ln(1/9) / ln(1/3)
=> x = 2

Answer 6

Pepsa, you are correct.
