Show that solving the equation 3^2x=4 by taking common logarithms of both sides is equivalent to solving it by taking logarithms
Sophie [7]

Answer:

Step-by-step explanation:

Case I:  use common logs:

 2x log 3 = log 4, or 2x(0.47712) = 0.60206

 Solving for x, we get 0.95424x = 0.60206, and then x = 0.60206/0.95424.

 x is then x = 0.631

Case II:  use logs to the base 3:

 2x (log to the base 3 of 3) = (log to the base 3 of 4)

 This simplifies to 2x(1) = 2x = (log 4)/log 3 = 1.262.  Finally, we divide this

 result by 2, obtaining x = 0.631

RideAnS [48]

Answer:

it is 114

Step-by-step explanation:

you do distributive property and since there’s no number it counts as a 1 so then you had 8+5 and you get 13 then you times that by 9 then subtract that answer with 3.
