log_{9}(b+7)-9=-8

lo g_{9} (b + 7) - 9 = - 8

b = 2

Solution steps

lo g_{9} (b + 7) - 9 = - 8

Move

9

to the right side

lo g_{9} (b + 7) = 1

Apply log rules

b + 7 = 9

Solve

b + 7 = 9 : b = 2

b = 2

Verify Solutions:

b = 2

True

The solution is

b = 2

lo g_{4} (x) - lo g_{4} (9) = 1

lo g_{4} (3 x) = 2.2

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

x, ln (x) = - 0.123

x + 2 x ln (x) = 0
