@d3v13

OpenStudy (anonymous):

i dont understand how to solve it with the index...

OpenStudy (anonymous):

16=2^4

OpenStudy (anonymous):

54=2*(3^3)

OpenStudy (anonymous):

so we can write the whole equation as

OpenStudy (anonymous):

\[3\times(2^{4/3}) + 3^{3/3}\times(2)^{1/3}\]

OpenStudy (anonymous):

\[3\times2^{1/3}(2+1)\]

OpenStudy (anonymous):

\[3^{2}\times2^{1/3}\]

OpenStudy (anonymous):

why is it 3^2?

OpenStudy (anonymous):

3times3

OpenStudy (anonymous):

=3times(2+1)

OpenStudy (anonymous):

so thats the final answer?

OpenStudy (anonymous):

yep

OpenStudy (anonymous):
