log_{8}(28k-20)+15=18

lo g_{8} (28 k - 20) + 15 = 18

k = 19

Solution steps

lo g_{8} (28 k - 20) + 15 = 18

Move

15

to the right side

lo g_{8} (28 k - 20) = 3

Apply log rules

28 k - 20 = 512

Solve

28 k - 20 = 512 : k = 19

k = 19

Verify Solutions:

k = 19

True

The solution is

k = 19

2 ln (x) = ln (2) + ln (x + 4)

lo g_{5} (x + 10) = 2

\frac{- 2 ln ( x ) + 1}{x ^{3}} = 0

lo g_{4} (x - 9) = 2

lo g_{10} (2 x + 3) = lo g_{10} (45) - lo g_{10} (3)
