Question 397899
 the square root of 5z multiplied by the square root of 5 minus the squareroot of z
{{{sqrt(5z) * sqrt(5) - sqrt(z)}}}
:
I don't see an equal sign here so it is not an equation, we can try to simplify it.
{{{sqrt(5*5z) - sqrt(z)}}}
which is
{{{5sqrt(z) - 1sqrt(z)}}} 
like terms,
{{{4*sqrt(z)}}}
