2log_{2}(x)+5=21

2 lo g_{2} (x) + 5 = 21

x = 256

Solution steps

2 lo g_{2} (x) + 5 = 21

Move

5

to the right side

2 lo g_{2} (x) = 16

Divide both sides by

2

lo g_{2} (x) = 8

Apply log rules

x = 256

Verify Solutions:

x = 256

True

The solution is

x = 256

lo g_{5} (x + 7) + lo g_{5} (x - 4) = 3

∣ ln (x + 3) ∣ = 1

lo g_{3} (4) + lo g_{3} (x) = 1

7.4 = lo g_{10} (x)

y, ln (y) = e^{x} + ln (x)
