Question 288386
{{{(x)^(4/3)=81}}} (x to the 4/3 power=81)
I used
{{{(x)^(4/3)=81}}}
{{{(2x)^(1/3)=81}}}  **** this is not good
------------------------
{{{x^(1/3) = 3 }}} is better
Then x = 27
-------------
Also, x = -27
-------------
There are other solutions with complex numbers, but this is proably sufficient for now.
-------------
{{{(2x)^(2/3))^(1/3)=81^(2/3)}}}
which made
{{{3x=(81)^(2/3)}}}
and then divided by 3, so
{{{x=(27)^(1/3)}}}
Does this look right?
