Answer:
Step-by-step explanation:
I don not understand what is for 4 here. So there are 2 cases:
Case 1: If you mean: log[4(x+20)]= 3
We know 3 = log(10^3)= log(1000)
So we have log[4(x+20)]= log(1000)
so 4(x+20)= 1000
and x+20 = 1000/4
x+20 = 250 and finally x= 250-20, x=230
The solution is 230.
Case 2; If you mean that 4 is the base of logarithm.
and we know that
So we have
and x+20 = 81
or x= 81-20
x=61
The answer is 61.
Hope that useful for you, both cases.
