Question

If $open parentheses 4 close parentheses to the power of log subscript 9 end subscript invisible function application 3 end exponent plus open parentheses 9 close parentheses to the power of log subscript 2 end subscript invisible function application 4 end exponent equals open parentheses 10 close parentheses to the power of log subscript x end subscript invisible function application 83 end exponent comma$ then $x$ is equal to

2
3
10
30

The correct answer is: 10

$open parentheses 4 close parentheses to the power of log subscript 9 end subscript invisible function application 3 end exponent plus open parentheses 9 close parentheses to the power of log subscript 2 end subscript invisible function application 4 end exponent equals open parentheses 10 close parentheses to the power of log subscript x end subscript invisible function application 83 end exponent$
$rightwards double arrow open parentheses 4 close parentheses to the power of fraction numerator 1 over denominator 2 end fraction log subscript 3 end subscript invisible function application 3 end exponent plus open parentheses 9 close parentheses to the power of 2 end exponent log subscript 2 end subscript invisible function application 2 equals open parentheses 10 close parentheses to the power of log subscript x end subscript invisible function application 83 end exponent rightwards double arrow 2 plus 81 equals open parentheses 10 close parentheses to the power of log subscript x end subscript invisible function application 83 end exponent rightwards double arrow 83 equals open parentheses 10 close parentheses to the power of log subscript x end subscript invisible function application 83 end exponent$
$rightwards double arrow x$
$equals 10$
