no
OpenStudy (kuoministers):
now to write 5 sqrt x in indices form?
OpenStudy (anonymous):
\[x^{5}\]
OpenStudy (kuoministers):
\[\sqrt[5]{x} = x ^{\frac{ 1 }{ 5 }}\]
this is the same thing ok?
OpenStudy (anonymous):

if you want to get rid of \[x ^{\frac{ 1 }{ 5 }} \]
you would multiply the whole equation by
the power of 5
OpenStudy (anonymous):
\[(x ^{1/5}+1=3)^{5}\]
OpenStudy (anonymous):
should you subtract 1 from both sides first
OpenStudy (anonymous):
thank you but I have to show my work
OpenStudy (kuoministers):
well the equation you wrote maybe wrong :P

@hartnn
can you please help i think i might need help :P
hartnn (hartnn):
yes, first you need to subtract 1 on both sides.
hartnn (hartnn):
x^(1/5) =2
gives x= 2^5
OpenStudy (kuoministers):
omg.... i am a idiot...
Yes if you subtract 1 from both sides yes it would work...
