=SQRT(5)*SQRT(2)+SQRT(8) is 5.99070478491457
320 = 64(5) =8 radical 5.,,....or 8 times the square root of 5!
The square root of 2.56 is rational. This is because 2.56 can be expressed as 256/100, which simplifies to 64/25. The square root of 64 is 8 and the square root of 25 is 5, so the square root of 2.56 is 8/5, which is a rational number.

Expressed in root form, 5 sqrt(18) - 7 sqrt(8) = sqrt(2)
Rounded to two decimal places, 8 sqrt(5) - 5 sqrt(54) = 18.85
8 times the square root of 5
17 plus 8 is 25, and the square root of 25 is 5. Alternatively, the square root of 17 is about 4.123; adding 8 to that gives about 12.123.
