ans is 8 as fifth root and raised to power 5 cancel each other out as they r opposite operations
OpenStudy (anonymous):
what is the exponential form for that?
OpenStudy (anonymous):
8^5/5 or 8^1
OpenStudy (anonymous):
THANK YOU , can you help me with the others? i still have , 9 questions here XD pls?

OpenStudy (anonymous):
\[\left( \sqrt[5]{243} \right)^{2}\]
OpenStudy (anonymous):
\[\sqrt[5]{243} = (3^{5})^{1/5} = 3^{5*1/5} = 3^{1}\]

243 = 3^5
\[\sqrt[5]{243}=3\]
\[(\sqrt[5]{243})^2=3^2=9\]
OpenStudy (anonymous):
thanks
OpenStudy (kira_yamato):
Anymore?
OpenStudy (anonymous):
yap, wait
OpenStudy (anonymous):
\[(\sqrt[5]{243})^{2} = [(3^5)^1/5]^2 = (3^5/5)^2 = 3^2\]

\[=(1/4)^3=1/64\]
OpenStudy (anonymous):
thanks.. \[\left[ 1/2\left( 1/8 \right) \right]^{1/4}\]
OpenStudy (kira_yamato):
\[=\left( \frac{1}{16} \right)^{1/4}=1/2\]

thanks.. \[\left( 27 2/3 \right)^{-1}\]
OpenStudy (anonymous):
thats 27 and two thirds
OpenStudy (kira_yamato):
\[\left( 27 \frac{2}{3} \right)^{-1}=\left(\frac{83}{3} \right)^{-1}=\frac{3}{83}\]
OpenStudy (anonymous):
thanks.. how do you insert fractions? XD
OpenStudy (kira_yamato):
Just key in frac{"numerator"}{"denominator"}

thank you, .. \[10 {3}/{4}. 10 {1}/{4}\]
OpenStudy (anonymous):
grrr,, still cant
OpenStudy (anonymous):
thats 10 and 3 fourths thanks :D
OpenStudy (kira_yamato):
\[10 \frac{3}{4} \times 10 \frac{1}{4}?\]
OpenStudy (kira_yamato):
is that what you mean?
