xapprox0.053

Explanation:

First the the log of both sides:
53^(x+1)=65.4
log53^(x+1)=log65.4
Then because of the rule loga^b=bloga, we can simplify and solve:
(x+1)log53=log65.4
xlog53+log53=log65.4
xlog53=log65.4-log53
x=(log65.4-log53)/log53
And if you type this into your calculator you get:
xapprox0.053
