root 3 = 1.732 (use your calculator)
root 5 = 2.236
root3 + root5 = 3.968
=========================
sqrt(4) = 2 sqrt(9) = 3 Therefore, the square root of 4 plus the square root of 9 is equal to 2 + 3 = 5.

The square root of 27 plus the square root of 5 = 7.4322204
if you take out the word ''quantity'' your answer is 25.02725024

It is 2*sqrt(5).
Square root of 3=1 so 1+4=5
5 Square root 3. square root 27 = square root 9*3 = 3square root 3 3square root3 + 2square root3 = 5Square Root3 because both have a square root 3.
There is no square root of -75. If it's 75, that is 5 square root 3.

You can always add radicals, but you can't simplify unless the radicands have a common factor. For example, the square root of 20 plus the square root of 45 equals 2 times the square root of 5 plus 3 times the square root of 5, which is 5 times the square root of 5.
