C-18
√324= √2^2•3^4= √2^2•√3^2•3^2= √2^2•√3^2•√3^2=2•3•3=18
159
10 squared is 100
Do the 5+3 next to get 8 then square the 8 to get 64
That leaves you with 100+64-5=159
3 is correct , base is never equal to 1 cause all of solves of logarithm will be 0
Answer:
Divide both sides by 3
∣x−1∣≥12/3
Simplify 12/3 to 4
∣x−1∣≥4
Break down problem into 2 equations
x−1≥4
(x−1)≥4
Then solve...
ANSWERS:
x≥5
x≤-3

all you have to do next is add all of them in one equation and equate them to 18
when you find x, replace in each expression to get your answers
