Verified answer

0.5 (bcause sq rt of 5 is 2.2 and sq rt of 3 is 1.7)

It rounds to 1/4.

hmmmh.. not sure my calculation ..let me try 1st..

(Square root of) 5 - (Square root of) 3

------------------------------...

2

using calculator, (5) ½ = 2.23 and (3) ½ =1.73

so, (5) ½ - (3) ½

= (2.23 - 1.73) ÷ 2

= 0.5 ÷ 2

= 0.25 (I guess!)

well the answer is 1.807746993......
