Question 144389

{{{sqrt(5vz^20)}}} Start with the given expression



{{{sqrt(5)sqrt(v)sqrt(z^20)}}} Break up the root



{{{sqrt(5)*sqrt(v)*z^10}}} Simplify {{{sqrt(z^20)}}} to get {{{z^10}}}



{{{z^10*sqrt(5)*sqrt(v)}}} Rearrange the terms



{{{z^10*sqrt(5*v)}}} Combine the roots




So {{{sqrt(5vz^20)}}} simplifies to {{{z^10*sqrt(5*v)}}}. In other words, {{{sqrt(5vz^20)=z^10*sqrt(5*v)}}} as long as "v" and "z" are positive.




--------------------------


You can't solve 3vz-2+4 since it is NOT an equation (it needs an equals sign). Also, if there was an equals sign, what variable are you solving for?
