logarithms!!?

Question

i need help finding the domain and solving
1. 3 log(base 5)x=1.5

and find the domain in

y=log (2-x)

all procedure please
and thank you

all wrong the 3 log x is log x power of 3

Answer 1

log(5)x=1.5/1.3=1.154
5^1.154=x
x=6.41

the domain is 2-x>=0
x<=2

Answer 2

3 log(base 5)x=1.5
log (base 5) x = .5
x = 5^.5 = root 5

domain {x such that s is an element of real numbers, x greater than/equal to 0}

y= log (2-x)
assuming base 10,

10^y = (2-x)
2-10^y= x
domain {x less than 2}

argument of log can never be negative.

Answer 3

log_5 x = 0.5
x = 5^0.5 = 2.23
domain of log is x> 0

Domain x < 2
