solvefor x,2ln(8x+9)-1=-5

solve for

x, 2 ln (8 x + 9) - 1 = - 5

x = \frac{1 - 9 e ^{2}}{8 e ^{2}}

Decimal Notation

x = - 1.10808 \dots

Solution steps

2 ln (8 x + 9) - 1 = - 5

Move

1

to the right side

2 ln (8 x + 9) = - 4

Divide both sides by

2

ln (8 x + 9) = - 2

Apply log rules

8 x + 9 = \frac{1}{e ^{2}}

Solve

8 x + 9 = \frac{1}{e ^{2}} : x = \frac{1 - 9 e ^{2}}{8 e ^{2}}

x = \frac{1 - 9 e ^{2}}{8 e ^{2}}

Verify Solutions:

x = \frac{1 - 9 e ^{2}}{8 e ^{2}}

True

The solution is

x = \frac{1 - 9 e ^{2}}{8 e ^{2}}

lo g_{49} (x) = - \frac{1}{2}

y, x = lo g_{10} (y) + 5

ln (x^{2} - 24) = ln (10) + ln (x)

x = 1 0^{l o g_{10} (\frac{1}{x})}

0 = - lo g_{3} (x + 4)
