ln (y^{2}) = ln (y + 3) + 2

y = \frac{e ^{2} + e ^{4} + 12 e ^{2}}{2}, y = \frac{e ^{2} - e ^{4} + 12 e ^{2}}{2}

Solution steps

ln (y^{2}) = ln (y + 3) + 2

Apply log rules

y^{2} = (y + 3) e^{2}

Solve

y^{2} = (y + 3) e^{2} : y = \frac{e ^{2} + e ^{4} + 12 e ^{2}}{2}, y = \frac{e ^{2} - e ^{4} + 12 e ^{2}}{2}

y = \frac{e ^{2} + e ^{4} + 12 e ^{2}}{2}, y = \frac{e ^{2} - e ^{4} + 12 e ^{2}}{2}

Verify Solutions:

y = \frac{e ^{2} + e ^{4} + 12 e ^{2}}{2}

True

, y = \frac{e ^{2} - e ^{4} + 12 e ^{2}}{2}

True

The solutions are

y = \frac{e ^{2} + e ^{4} + 12 e ^{2}}{2}, y = \frac{e ^{2} - e ^{4} + 12 e ^{2}}{2}

x, y = ln (3 x)

x^{2} ln (x) - 9 ln (x) = 0

x, ln (x) = z

lo g_{5} (x + 1) = 2 + lo g_{5} (3 x - 2)

ln ∣ x ∣ = ln (x^{2})
