wow great
OpenStudy (anonymous):
do not take the square root of the exponents, take half of them
OpenStudy (anonymous):
for example, although \(\sqrt{100}=10\) \[\sqrt{x^{100}}=x^{50}\]

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 (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):

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

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

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\[805\%, 8\tfrac{1}{20}\]
