with?

OpenStudy (anonymous):

simplify \[(\sqrt{3)}(\sqrt[5]{3})\]

OpenStudy (here_to_help15):

i cant seem to uinderstand that??

OpenStudy (anonymous):

have you learned about negative and fraction exponents?

OpenStudy (anonymous):

yes but that was a long time ago

OpenStudy (anonymous):

First convert the radicals to exponents \[3^{\frac{ 1 }{ 2 }}\times3^{\frac{1}{5}}\]

OpenStudy (anonymous):

Then all you do is add the exponents since the bases are the same

OpenStudy (anonymous):

So you will need to find a common denominator which will be 10

OpenStudy (anonymous):

\[\frac{ 1 }{ 2 }*\frac{ 5 }{ 5 }+\frac{ 1 }{ 5 }*\frac{ 2 }{ 2 }\] Then you will have \[\frac{ 5 }{ 10 }+\frac{ 2 }{ 10 }\]

OpenStudy (anonymous):

is it the last one

OpenStudy (anonymous):

last one what?

OpenStudy (anonymous):

the last answer choice

OpenStudy (anonymous):

You didn't post any answer choices that I can see

OpenStudy (anonymous):

sorry i forgot to post the answers

OpenStudy (anonymous):

3 to the power of 1 over 10 3 to the power of 3 over 5 3 to the power of 9 over 10 3 to the power of 7 over 10

OpenStudy (anonymous):

\[3^{\frac{ 7 }{ 10 }}\]

OpenStudy (anonymous):

so, yeah you are correct

OpenStudy (anonymous):

ok thanks
