3 to the power of 1 simplified, is just 3.
Answer:
13a
Step-by-step explanation:
9a + 3a + a = 13a
The parent function that is f(x) = log(x) is transformed firstly, to log(x+2)
since, we can see after that we can directly convert it to log(2x+4)
and after one reflection it will become log(-2x-4)
°ω° Hope this helps :)
Good luck bud :D
I hope this helps you
2x+8= -7-3x
5x= -15
x= -3
Hello !
Here are some rules for logarithms : log ₐ b = n ⇔ aⁿ = b
log ₐ aⁿ = n
log ₐ (b·c) = logₐ b + log ₐ c
log ₐ bⁿ = n· log ₐ b ____________________________________________________
25=5²
625=5⁴
100 = 5² · 2²
____________________________________________________
(log₅ 25 + log₅ 625) / log₅100 =
(log₅ 5²+ log₅ 5⁴) / log₅ (5² · 2²) =
(log₅ 5²+ log₅ 5⁴) /( log₅ 5² + log₅ 2²) =
(2 + 4)/(2+log₅ 2² ) =
6/ (2+2·log₅2)=
6/2 + 6/ (2·log₅2) =
3+ 3/log₅2
log₅2 = 0.5
So 3+ 3/log₅2 = 3 + 3/0.5 =3 + 6 = 9
Answer : 9
