How can i solve surd form

Answer 1

If you are talking about square roots, then first factor out the perfect squares
√360 = √(2^3 * 3^2 * 5) = √(2^2 * 2 * 3^2 * 5)
Now, √x^2 = x, so this becomes
2*3√(2*5) = 6√10

There are also many examples and discussions of the topic online. That's the best place to start when you have a general question like this.
