Question

solve the surd : √3(√5+2√3)​

Answer 1

Answer:

The order of a surd indicates the index of root to be extracted.

In a−−√n, n is called the order of the surd and a is called the radicand.

For example: The order of the surd z√5 is 5.

(i) A surd with index of root 2 is called a second order surd or quadratic surd.

The surds which have the indices of root 2 are called as second order surds or quadratic surds. For example√2, √3, √5, √7, √x are the surds of order 2.

Example: √2, √5, √10, √a, √m, √x, √(x + 1) are second order surd or quadratic surd (since the indices of roots are 2).

Answer 2

Step-by-step explanation:

2/√5+√3 + 1/√3+√2-3/√5+√2

= (√5-√3)+(√3-√2)-(√5-√2)

= 0
