Question

What is the solution of

log6x + log6(x + 5) = 2?

Answer 1

Doesn't have solution.

Explanation:

x ≠ 0; x > 0 (I)

x - 5 > 0

x > 5 (II)

`log_6 x + log_6 (x + 5) = 2 \\\ log_6 [x(x + 5)] = 2 \\\ x^2 + 5x = 36 \\\ x^2 + 5x - 36 = 0 \\\ \Delta = 5^2 - 4.1.(- 36) \\\ \Delta = 169 \\\ √(\Delta) = \pm 13 \\\ x' = (- 5 + 13)/(2) \\\\ x' = 4 \\\ x`

Then, this expression doesn't have solution.

I Hope I've helped you.
