how would I do 2 divided by the cube root of 20

Question

2÷³√20

Answer 1

What is 2 cubed?  That would be 8.  So if we rewrite this expression so that we have like radicals, we get

 

³√(8) / ³√(20)

 

 

Applying the rules of radicals,

 

³√(8 / 20) =

 

³√(2 / 5)

 

 

The exact form of the solution is the  cube-root of 2/5.

Answer 2

is the question asking to rewrite it or solve it?
if you want fractional exponents only: 2 ÷ 20^1/3
if you want negative exponents too: 2(20^-1/3)
if you want to solve it, plug any of these into your calculator and round the decimal point
