Question

solve with the help pf logarithm:-

log(x²-3x)=1

You have to find x ​

Answer 1

Answer:

x = 5

Step-by-step explanation:

$log( {x}^{2} - 3x ) = 1 \\ = > {x}^{2} - 3x = 10 \\ = > {x}^{2} - 3x - 10 = 0 \\ = > x = \frac{3± \sqrt{ {3}^{2} + 4 \times 10 } }{2} \\ = > x = \frac{3±7}{2} \\ = > x = 5 \: or \: - 2$

since log arguments can't be negative

x = 5 is the right answer

Hope it helps :D
