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.
It might be best to answer this with an example. Look at the square root of 8. To simplify it we notice that 8 is 2x4 and that 4 is a perfect square. So we can simplify the square root by taking the 4 out of the radical sign and writing it as 2xsquare root of 2. Perhaps a better way to think of this is that is you have square root of a x square root of b, that is the square root of (ab). So if we have square root of 8 that is the same as square root of 4 x square root of 2 and square root of 4 is 2 so the answer is 2xsquare root of 2. In general, look for perfect squares and factor them out of the number so they can be removed from the square root.

The square roots of 13 cannot be simplified.
Replace the radical sign with the exponent 0.5. For example sqrt(7) = 70.5
To add simplified square roots, first simplify each individual square root expression. Then, if the numbers inside the square roots are the same, add or subtract the numbers outside the square roots. Finally, combine the numbers inside the square roots if possible. For example, to add √8 and √18, simplify them individually as 2√2 and 3√2. Since the numbers inside the square roots are the same, add 2 and 3 to get 5√2 as the final result.
All prime numbers have irrational number square roots, so if you try to find the square root of a non-perfect square number use them to simplify it. For example, ±√125 = ±√25*5 = ±5√5 (when you want to show both the square roots) √72 = √36*2 = 6√2 √-27 = √-9*3 = 3i√3

Sure. the square root of 6 times 4 square roots of 6 is the same as the square root of 6 to the power of five which can be reduced to 6 squared times the square root of 6. The resulting answer is 36 root 6.

Look for the largest square number in its factors. The square root of 512 is equal to the square root of 2 times the square root of 256. The square root of 256 is 16. The square root of 512 simplifies to 16 times the square root of 2.
The square roots are -1.07 and +1.07The square roots are -1.07 and +1.07The square roots are -1.07 and +1.07The square roots are -1.07 and +1.07
Square roots can be multiplied by multiplying the numbers under the square root. For example, sqrt(4) * sqrt(5) = sqrt(4*5) = sqrt(20). They can then be simplified by doing the opposite, splitting them apart. sqrt(20) = sqrt(4) * sqrt(5) = 2 * sqrt(5).
The square root of 91x cannot be simplified.
square inches do not have square roots only number have square roots.
Perfect square roots are square roots that have a whole number that can go into it perfectly. Nonperfect square roots are square roots that have decimal numbers going into it. Example: Perfect Square Root: 144- Square Root: 12 Nonperfect Square Root: 24- Square Root: About 4.89
