Hope u like my process..
-_-_-_-_-_-_-_-_-_-_-_-_-_
$log_{x}(100) - 2 log_{x}(2) = 2 \\ or. \: log_{x}(100) - log_{x}(2 ^{2} ) = log_{x}( {x}^{2} ) \\ or. \: log_{ x}( \frac{100}{2 \times 2} ) = log_{x}( {x}^{2} ) \\ or. \: 25 = {x}^{2} \\ or. \: {x}^{2} - 25 = 0 \\ or.(x - 5)(x + 5) = 0 \\ .........so.......$
X= ±5
