A surd in the form a√b cannot, in general, be simplified.
sqrt(a)+sqrt(b) is different from sqrt(a+b) unless a=0 and/or b=0. *sqrt=square root of
sqrt(a2 + b2) can't be simplified. Neither can (a2 + b2) .
b over the square root of 5 The square root of 5b squared is 5b, and the simplified form of the square root of 125 is 5 root 5. The 5s then cancel out leaving b over the square root of 5.
It is b^2*sqrt(b).

The square root of a/b is equal to the square root of a divided by the square root of b. I hope this helps you.
A surd in the form a√b cannot, in general, be simplified.
Yes, that is correct. It is one of the basic properties of surds, and is used in many identities and some equations, to simplify and calulate and prove.
-b + or - the square root of b squared - 4ac over/divided by 2a
if B*B = a, then B is square root of a
Make use of the property that sqrt(ab)=sqrt(a) x sqrt(b) and try to find an 'a' or 'b' that can be expressed as a whole number; these combinations of a square root and a coefficient are called surds.e.g. In square root form, sqrt(18) = sqrt(9 x 2)= sqrt(9) x sqrt(2). This, in surd form, is 3 x sqrt(2).Note that the property sqrt(ab) = sqrt(a) X sqrt(b) does not hold for negative radicands (imaginary numbers) unless negative roots are accounted for. For example, it is known that sqrt(-1) X sqrt(-1) = -1. The property mentioned above would imply that sqrt(-1) X sqrt(-1) = sqrt(-1 X (-1) = sqrt(1) which is only true if the square root of 1 is taken to be either 1 or -1.
To simplify a root, you need to be aware that the root of ab is the same as the root of a multiplied by the root of b. To simplify we need to find the prime factors of the number and identify any repeated factors. In this case, we have 850, which is expressed as 2x5x5x17. The 5 comes twice, and so we can divide by 25 to give 34. There are no more repeated factors. Therefore the square root of 850 is 5 the square root of 34.
sqrt(a)+sqrt(b) is different from sqrt(a+b) unless a=0 and/or b=0. *sqrt=square root of
There is an ambiguity whether you square the sum of a plus b, or only b. In any case, I don't think you can simplify this expression.
sqrt(a2 + b2) can't be simplified. Neither can (a2 + b2) .
6x² - 17x +12 = Quadratic equation X = (-b +/- (square root of b² - 4ac)) divided by 2a X = (--17 +/- square root of 289-288)) divided by 12 X = 1.5 or 1.333333 recurring
