Square root of 3=1 so 1+4=5
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.
x=1/2(-1-square root of 21) and x=1/2(square root of 21 -1)
Using the quadratic equation formula the values of x are: x = -2 - the square root of 5 and also x = -2 + the square root of 5
Square root of 25= 5. 5 + 144 + 13 = 162.
Square root of 3=1 so 1+4=5
The square root of 27 plus the square root of 5 = 7.4322204
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.
square root -5 minus 14 or - square root -5 minus 14
x = 7

5
The square root of 9 is 3, and the square root of 16 is 4. Adding these together, 3 + 4 equals 7. Therefore, the square root of 9 plus 16 is 7.
Square root of 25= 5. 5 + 144 + 13 = 162.
5 times the square root of two over 3 times the square root of two equals 5/3
