Answer:

\displaystyle x =   3.97

Step-by-step explanation:

we are given a exponential equation

\displaystyle  {3}^{x}  = 78

we want to figure out x

remember that,

\displaystyle   \log_{a}( {a}^{c} )   = c

thus

take \log_3 both sides:

\displaystyle   \log_{3}( {3}^{x} ) =   \log_{3}(78)

use the formula:

\displaystyle x =   \log_{3}(78)

by using calculator

\displaystyle x =   3.97
