Answer:
Step-by-step explanation:
Some facts to establish before we try to solve: 
and another way of writing 
is 
. Also order of operations: PEMDAS
For the first option:
We solve what is in the parenthesis: 2*2=4*2=8*2=16*2=32*2=64 so , which is another way to write
For the second option: If the square root of 64 is 8, the there is no way we can multiply another value by it.
The third option: When dealing with square roots, we can solve the inside first and then take the square root:
definitely not 64 (though if you're curious it's 4096)
The fourth: Another way to write the square root is to raise the value to the 1/2 power so
Which is the same as
Fifth: Like the third, we solve the inside of the square root first
16*4= 64 and then
Sixth: We need a nice whole number (8), and 
has no clean roots, so its result will have decimals. It can't be our answer

Answer:
x₁ = 3,29296875
x₂ = 3,276659786
x₃ = 3,279420685
Step-by-step explanation:
This is a recurrent relationship between xₙ₊₁ and xₙ
To get x₁, write the formula with n=0:
Then fill in what you know, x₀=3.2. This gives you x₁.
Repeat for n=1,... and so forth.
Excel can do this effectively, see picture.
Answer: $1.5
Step-by-step explanation:
subtract 3.9 from 18.9
you get 15, divide by 10
=1.5
