PLEASE CHECK MY ANSWERS

OpenStudy (rootbeer003):

OpenStudy (anonymous):

no

OpenStudy (rootbeer003):

wow great

OpenStudy (anonymous):

do not take the square root of the exponents, take half of them

OpenStudy (anonymous):

for example, although \(\sqrt{100}=10\) \[\sqrt{x^{100}}=x^{50}\]

jimthompson5910 (jim_thompson5910):

Another Example \[\Large \sqrt{x^{20}} = x^{20/2} = x^{10}\]

OpenStudy (rootbeer003):

OpenStudy (anonymous):

they are trying to confuse you by making the exponents perfect squares, don't fall for it another example \[\sqrt{x^6}=x^3\]

OpenStudy (rootbeer003):

iz did

OpenStudy (anonymous):

you took the square root of the exponents, don't do that divide the exponents by 2

OpenStudy (anonymous):

what is half of 36?

OpenStudy (rootbeer003):

16

OpenStudy (rootbeer003):

32

OpenStudy (anonymous):

right

OpenStudy (anonymous):

those are your exponents

OpenStudy (rootbeer003):

aandd

OpenStudy (anonymous):

and.. which choice has those as exponents?

OpenStudy (rootbeer003):

c

OpenStudy (anonymous):

um no which one has exponents 18 and 32?

OpenStudy (rootbeer003):

dddddddddddddddd

OpenStudy (anonymous):

bingo

OpenStudy (rootbeer003):

OpenStudy (rootbeer003):

come back we aint done here

OpenStudy (anonymous):

lol i see that ' also this one is wrong

OpenStudy (rootbeer003):

b?

OpenStudy (anonymous):

8.05 turn it to a decimal move the decimal to places right

OpenStudy (anonymous):

now you are guessing move the decimal two places to the right, what do you get?

OpenStudy (rootbeer003):

its d

OpenStudy (anonymous):

yes it is

OpenStudy (rootbeer003):

i was correct

OpenStudy (anonymous):

since \(8.05=805\%\) and \(.05=\frac{5}{100}=\frac{1}{20}\) not \(\frac{1}{2}\)

OpenStudy (anonymous):

D again

OpenStudy (rootbeer003):

that lag was beautiful

OpenStudy (rootbeer003):

i got that one wrong it wasent d

OpenStudy (rootbeer003):

it was c. which was my secound choice

OpenStudy (anonymous):

no, it is D i don't care what they say

OpenStudy (rootbeer003):

wow

OpenStudy (anonymous):

\[8.05=8\tfrac{1}{20}\] for sure

OpenStudy (anonymous):

\[8.5=8\tfrac{1}{2}\]

OpenStudy (rootbeer003):

let me give you a lecture

OpenStudy (anonymous):

i am pretty sure i know my decimal places eight point five is eight and a half eight points zero five is eight and one twentieth

OpenStudy (anonymous):

lecture away, as long as it comes with a root beer rolex

OpenStudy (rootbeer003):

it wont let me draw that crap hold on

OpenStudy (anonymous):

lol i am holding D is correct anyways either you put in C by mistake, or the system is wrong

OpenStudy (rootbeer003):

OpenStudy (rootbeer003):

i was correct

OpenStudy (rootbeer003):

OpenStudy (rootbeer003):

:))

OpenStudy (anonymous):

lol we were looking at a totally different question the one with \(8.05\)

OpenStudy (rootbeer003):

WHAT

OpenStudy (rootbeer003):

bruhh

OpenStudy (rootbeer003):

u said d

OpenStudy (anonymous):

the question you posted had an \(8.05\) in it and the question was to write it as a mixed number and a percent

OpenStudy (rootbeer003):

AWE THE CRAP

OpenStudy (anonymous):

the answer was D\[805\%, 8\tfrac{1}{20}\]

OpenStudy (rootbeer003):

I POSTED THE WRONG ONE

OpenStudy (anonymous):

pay attention!

OpenStudy (rootbeer003):

so stay put

OpenStudy (anonymous):

clint eastwood's root beer

OpenStudy (rootbeer003):

you already showed me that

OpenStudy (rootbeer003):

OpenStudy (rootbeer003):

am i right or naw

OpenStudy (anonymous):

yes

OpenStudy (rootbeer003):

im always right

OpenStudy (anonymous):

yeah sure

OpenStudy (rootbeer003):

OpenStudy (rootbeer003):

i got 3.2..

OpenStudy (anonymous):

nope

OpenStudy (rootbeer003):

im always right

OpenStudy (anonymous):

http://www.wolframalpha.com/input/?i=sqrt%288%29

OpenStudy (anonymous):

yeah but \(16-8=8\)

OpenStudy (rootbeer003):

http://www.wolframalpha.com/input/?i=sqrt%2810%29

OpenStudy (rootbeer003):

o wow

OpenStudy (anonymous):

loll

OpenStudy (rootbeer003):

a

OpenStudy (anonymous):

should we start the lesson in subtraction?

OpenStudy (anonymous):

yeah A

OpenStudy (rootbeer003):

im always right

OpenStudy (rootbeer003):

OpenStudy (anonymous):

that time you actually are right

OpenStudy (rootbeer003):

im always right

OpenStudy (anonymous):

except when you aren't

OpenStudy (rootbeer003):

OpenStudy (rootbeer003):

my brain hurts

OpenStudy (anonymous):

this one you can do because you did the last one

OpenStudy (anonymous):

\[3+\sqrt{25}-\sqrt{12}\]

OpenStudy (anonymous):

what is \(\sqrt{25}\)?

OpenStudy (rootbeer003):

5

OpenStudy (anonymous):

and \(3+5=?\)?

OpenStudy (rootbeer003):

8

OpenStudy (anonymous):

and you just wrote that \(\sqrt{12}=2\sqrt3\) so what is the final answer?

OpenStudy (rootbeer003):

d

OpenStudy (anonymous):

you are always right

OpenStudy (rootbeer003):
