How do you solve these math questions? ? i really really need

.
in(x-4)^2 + 2 = 5

1/2((log base of x) 4 + log (base of x) (y)) - 3log (base of x) (z)

a savings account is increased by 15% annually. if it is started at $3, how long will it take until it reaches $15?

e^(in5x) = 20

log(4x-3) + 6 = 4

1 - 3^(2x) = -5

2in e / 2

log base of (1/4) (1/8)

y = log base of 4 (x+1)

y = -3^(x+1)
