50 = - 20 lo g_{10} (r)

r = \frac{1}{100 10}

Decimal Notation

r = 0.00316 \dots

Solution steps

50 = - 20 lo g_{10} (r)

Switch sides

- 20 lo g_{10} (r) = 50

Divide both sides by

- 20

lo g_{10} (r) = - \frac{5}{2}

Apply log rules

r = \frac{1}{100 10}

Verify Solutions:

r = \frac{1}{100 10}

True

The solution is

r = \frac{1}{100 10}

ln (4 x - 3) = 5

ln (4 x - 3) = 3

ln (4 x - 3) = 0

4 x lo g_{3} (4 x - 12) = 8

ln (a) = 8 ln (9) + 12 ln (3)
