ln(x^4-5x^2+4)=-1

Solution

ln (x^{4} - 5 x^{2} + 4) = - 1

Solution

x = \frac{5 e + 9 e ^{2} + 4 e}{2 e}, x = - \frac{5 e + 9 e ^{2} + 4 e}{2 e}, x = \frac{5 e - 9 e ^{2} + 4 e}{2 e}, x = - \frac{5 e - 9 e ^{2} + 4 e}{2 e}

+1

Decimal Notation

x = 2.02928 \dots, x = - 2.02928 \dots, x = 0.93915 \dots, x = - 0.93915 \dots

Solution steps

ln (x^{4} - 5 x^{2} + 4) = - 1

Apply log rules

x^{4} - 5 x^{2} + 4 = \frac{1}{e}

Solve

x^{4} - 5 x^{2} + 4 = \frac{1}{e} : x = \frac{5 e + 9 e ^{2} + 4 e}{2 e}, x = - \frac{5 e + 9 e ^{2} + 4 e}{2 e}, x = \frac{5 e - 9 e ^{2} + 4 e}{2 e}, x = - \frac{5 e - 9 e ^{2} + 4 e}{2 e}

x = \frac{5 e + 9 e ^{2} + 4 e}{2 e}, x = - \frac{5 e + 9 e ^{2} + 4 e}{2 e}, x = \frac{5 e - 9 e ^{2} + 4 e}{2 e}, x = - \frac{5 e - 9 e ^{2} + 4 e}{2 e}
