## anonymous 4 years ago How do you express this in simplest form: sqrt4.5

1. BTaylor

$\sqrt{4.5}=\sqrt{9/2} = \sqrt{9}/\sqrt{2}=3/\sqrt{2}$ If you need to rationalize the denominator, multiply both the numerator and denominator by sqrt(2) to get $(3\sqrt{2})/2$

2. anonymous

Well, the answer is suppose to be: $1.5\sqrt{2}$
