Answer:
x= -0.715
Step-by-step explanation:
6^x+2 = 10
<u>Apply the log rule:</u>
<em>a^X = Y</em>
<em>X log a = log Y</em>
<em>X = log a/log Y</em>
6^x+2 = 10
(x+2) log 6 = log 10
x+2 = log 10/log 6
x+2 = 1.285
x = 1.285 - 2
x = -0.715
Therefore, the second option is correct where x is equal to -0.715.
