Question 1007599: Are my answers and work correct for these questions?
Directions:Solve each of the following simple logarithmic equations. Show work.
17) log3 x = 4
logb(x)=y is equivalent to b^y=x
3^4= x
81=x
18) log5 (x + 2) = 3
5^3= (x-2)
125= 125-2
x=123
19) log2 (3x – 4) = 5
2^5= 3x-4
x= 12
20) logx 1000 = 3
x^3=1000
x= 10
