Question 840036
{{{p= 500 - 10x^(1/2)}}} when x = 2500
{{{p= 500 - 10(2500)^(1/2)}}}
if you know that the square root of 2500 is 50
{{{p= 500 - 10(50)}}}
{{{p= 500 - 500}}}
{{{p= 0}}}
if you do not see that the square root of 2500 is 50,
you can factor 2500.
{{{p= 500 - 10(25*100)^(1/2)}}}
apply ^1/2 to 25 and 100
{{{p= 500 - 10((25)^(1/2)*(100)^(1/2))}}}
{{{p= 500 - 10(5*10)}}}
{{{p= 500 - 10(50)}}}
{{{p= 500 - 500}}}
{{{p= 0}}}
