3.54 is the answer plz mark as brainliest

Answer 2

The idea is to get it in a form that has no square root in the

denominator.

To get it that way we make the number under the radical become a

perfect square.  The smallest perfect square we can make 2 into

by multiplying is 4. So to make the denominator become sqrt%284%29

instead of sqrt%282%29 we multiply the whole fraction by the "unit"

fraction sqrt%282%29%2Fsqrt%282%29 [it's a "unit" fraction because it

equals 1.]

5%2Fsqrt%282%29�sqrt%282%29%2Fsqrt%282%29

Multiplying tops and bottoms (bottoms under the radicals)

%285sqrt%282%29%29%2Fsqrt%284%29

Then the square root of 4 is just 2 so the final answer is

%285sqrt%282%29%29%2F2

and there is no square root in the denominator.
