n^(2/3)  = 216

 

Take each side to the 3/2 power

 

[n^(2/3)]^(3/2)   =  216 ^(3/2)  

 

n   =  [ √ 216 ] ^3

 

n = [ √ (36 * 6) ] ^3

 

n = [ 6  √6 ] ^3

 

n = 6^3 * (√6)^3 

 

n  =  216 * [√6 ]^2 * √6

 

n  =  216 * 6  * √6

 

n = 1296√6

 

I'll take those 5 pepperonies  !!!!

 

 

cool cool cool
