Question 144499
{{{sqrt(300) - sqrt(12) - sqrt(3)}}}
:
factor inside the radicals to reveal the perfect squares that are lurking inside there.
{{{sqrt(100*3) - sqrt(4*3) - sqrt(3)}}}
:
Extract the square root of these perfect squares
{{{10*sqrt(3) - 2*sqrt(3) - sqrt(3)}}}
:
Now we have like terms, just do the math
{{{7*sqrt(3)}}}
:
:
you can check this a on calc:
enter: {{{7*sqrt(3)}}} = 12.124355...
:
enter:
 {{{sqrt(300) - sqrt(12) - sqrt(3)}}} = 12.123355...
