If
is an integer, you can use induction. First show the inequality holds for
. You have
, which is true.
Now assume this holds in general for
, i.e. that
. We want to prove the statement then must hold for
.
Because
, you have
and this must be greater than
for the statement to be true, so we require
for
. Well this is obviously true, because solving the inequality gives
. So you're done.
If you
is any real number, you can use derivatives to show that
increases monotonically and faster than
.
So assuming the underlined decimal is the second 8, let's answer the question.
Hundreds: 0 | Tens: 8 | ones: 3 | . | tenths: 5 | hundredths: 8 | thousandths: 5 | 10 thousandths: 1
So since the second 8 is in the hundredths place, we know it's either B or C.
When we round for 5, we always round up, so the answer would be 83.59
So the answer is B.

X=⁻3 and x=1
because
a+b=2 which means a=3 and b=⁻1 which added up equals 2
a×b=⁻22 which means that 11 which is a×⁻2 which is b=⁻22
36/20 or simplified and as a mixed number would be:
1 and16/20
I think it may be the ability to get the correct/same answer (percision) to within 40 feet.
