Solve the equation in each of the following.log6(x + 4) - log6(x - 1) = 2

log6(x + 4) - log6(x - 1) = 2⇒ ⇒ (x + 4)(x - 1) = 62 = 6×6⇒ x + 4 = 6⇒ x = 6 - 4 = 2

Solve the equation in each of the following.
log₆(x + 4) - log₆(x - 1) = 2

log₆(x + 4) - log₆(x - 1) = 2

⇒

⇒ (x + 4)(x - 1) = 6² = 6×6

⇒ x + 4 = 6

⇒ x = 6 - 4 = 2
